Philips CorePro GU10 5-50W LED - £8.79

Soarer

Judging by a few other threads, people seem to be looking for good quality GU10 LED bulbs.
These Philips CorePro bulbs are reduced to £8.79 with free delivery. They're currently €22.50 in my local shop, and seem to be around the €20 mark from Irish e-tailers.

I've been in touch with LED Vista in Wexford, and after consulting with Philips, they'll do them for €11.99 a piece. Granted that's around €1.50 per bulb more than the Amazon price, but you're keeping the money in Ireland, etc.

A tenner a bulb is thereabouts the rate now. That €22.50 is disgraceful. Tell your "local shop" that they are the reason we hunt online for better prices. And i'd bet the shop owner would be top of the queue singing the old tune "Buy local, save jobs!"

They can all f**k off.

LED lighting prices have moved down fairly quickly - not really the fault of the store that they bought stock a few months ago and haven't re-ordered, though they'll have to take a hit. But interesting to see the Amazon rrp being £34.15 (about €41) - so the "local shop" has been well under the previous Amazon price up till now!

You'll see the better quality ones at €5-€8 soon enough in most places (already €5 in ikea for their latest version) and cheap unbranded ones for €3-€5.

GU10 Dimmable 330lm curently in Homebase for €6.49. (extra 20% off last week and will be repeated at end of Jan I believe.)

You have to have your eyes open to get the brigtestes ones.

They have 150lm, 250lm & 330lm.

The 150lm replace a 35watt halogen. The 250 & 330 replace the 50 watt halogen.

The 330lm are extremely bright.

For dimmable, you have to get the ones in a plasticmclamshell. Non dimmable are also 6.49 and are in a cardboard clamshell.

For some, the 330lm may be too bright especially if you have a lot of downlighters.

To give comparison - the 3.4w IKEA are 150lm. - so over twice the brightness.

Capt'n Midnight

Just a reminder of what's in the pipeline, real world efficiency will be less because of transformers and electronics, and the colour might not be to everyones linking but still it's 5 times the efficiency of the philips posted earlier.

http://www.cree.com/News-and-Events/Cree-News/Press-Releases/2013/February/276-LPW

Cree reports that the LED efficacy was measured at 276 lumens per watt, at a correlated color temperature of 4401 K and 350 mA.

For real world it's about 200Lm/Watt
http://www.electronics-eetimes.com/en/led-lamp-prototype-delivers-200-lumen-per-watt.html?cmp_id=7&news_id=222916471&vID=209

Philips researchers developed a tube lighting (TL) replacement TLED prototype that produces a record 200 lumens per watt of high-quality white light (compared with 100lm/W for fluorescent lighting and just 15lm/W for traditional light bulbs). This prototype TLED lamp is twice as efficient as predecessor lamps, basically halving the energy used.

So far none of the LED's listed here are 100Lm/W

If you like the colour or the switch on times then buy now, if the bulb will pay back the electricity in the next two or three years buy now, if not then wait for a year or two for cheaper, more energy efficient LED's or wait for larger discounts.

Yes you can get CFL's in GU10 but the price differential to LED isn't as big as for normal B22 bulbs so YMMV

I'm putting 23 LED's into our kitchen/dining area and got them all from this seller on Amazon, 1.2w each...

vibe666

I got a couple of these to test and very happy with the 330Lm output, it's a single COB LED with a nice warm and wide beam and very close to 50W GU10's compared side by side, and dimmable too was important for me as most of the time I have them down low anyway, so they're using even less juice.

if you didn't need them quite bright, they also do a nice looking dimmable 3.5w 250Lm one for £6.49 as well. http://www.lightmylife.com/Product/View/gu10vp6/GU10-LED-Bulb-3-5W-Spotlight-Extra-Wide-Beam-Angle--35W-Equivalent--250-Lumen.html

I'd also like to thank Capt'n Midnight for putting me onto the Osram DuLED dual CFL and LED bulbs. I wasn't able to find them cheaply in bricks and mortar shops, but they are available on Amazon for about £10 each, which although it seems expensive for a CFL, I've been finding that about 90% of the time, I only need to use the LED part which is only putting out 0.3W per bulb that gives off a similar light to a clear night with a big full moon, which is more than sufficient for most things during the night.

They are perfect for hallways, bedrooms and bathrooms, particularly if you have kids as they are bright enough to see to go for a pee, but not bright enough to wake you up too much in the middle of the night.

I especially like that they don't need any special light switches, you just turn it on once for the LED, then turn it off and back on within 5 seconds to switch to the CFL bulb.

As with all CFL's, 8W is fine for bedrooms and hallways, but go for the higher power ones for bathrooms or kitchens.

Just got five of these from Electric Ireland, €8.95 each and free shipping. They are excellent and Osram are a good brand.

They are twice the price of homebase!

Also, there are quite a few old model leds about, so be sure to go by lumens rather than what is claimed. And watch for ones that may not fit exactly into some fittings.

I would buy the osram halogens which are 35 watts with the brightness of 50 watts. LEDs are constantly going down in price and improving. There is no point buying a ton of expensive bulbs which will 4 times the price and half the light of LEDs in 5 years

That's awful advice.

The payback period is good. Even putting in expensive ones will pay for themselves fairly fast. The max you should pay is 10 a lamp. That will get you a Philips or equivalent

Eurosales were selling Philips masters for 8.65 last year, there probably cheaper now

Capt'n Midnight

Ah.. at 3 hours a day looks like the payback time for energy saving bulbs is about 1 year


If you have the 240V lights then you can get CFL's too, but like I said they aren't that much cheaper than LED's , so you might as well use which ever is the cheapest of the two. NB. today's LED's aren't more efficient thatn CFL's
( For normal bayonet bulbs use CFL's today and replace them with LED's when they are significantly more efficient than CFL's )


The big PITA is the 12V halogens running from non-regulated transformers. You can't easily replace with CFL and the 12V LED's are easily fried because they don't seem to have regulators that can stand the voltage. This is strange because they cost more than the 240V LED's which have built in regulators,, and because most 12V installs are non-regulated transformers.

It's nearly a case of changing the mains transformer to a regulated one , or just rewiring to use mains voltage. If you use them several hours a day it might be cheaper to get an electrician in to undo it.


Moral of the story is , with lighting always use the most simplest most standard bulb size you can.

galldar

Got these a couple of weeks ago (see attached), well pleased with the brightness and lighting angle. Much better than the cheap chinese ones I had fitted.
Work out about €8 inc VAT, think he said there's a five year warranty too.

LEDs should last longer though - I've found CFLs rarely last as long as is claimed on the box. Also CFLs can't be thrown in the bin as they contain mercury (I'm sure plenty of people do chuck them in the bin, but you shouldn't).

yes LED's should last longer, but no point because by then there will be better cheaper ones

and you can't throw any electronics in the bin, LED and CFL have to be handed in as WEE wherever you buy bulbs.

ted1

I don't think CFLs are comparable to LEDs especially with start up time.

Installing CFLs then replacing with LEDs doesn't make sense as the capital costs will be higher.
Due to life time of LEDs the market is smaller as lamps aren't replaced. So I can't see them reaching the price levels of incandescent as they'll want to keep making profits.

powerstation

I had this experience when replacing Ikea 12v G4 cabinet spot halogens with LED G4 bulbs from DX.

The LED G4's were rated for 12 VAC, and the board had a regulator IC, but after fitting them I discovered the Ikea AC transformer driver throttled the current, and the LED's only gave off a faint glow. I then (stupidly) tried to mix and match 1 halogen and 1 LED. The LED worked well for a few minutes but it's regulator chip overheated and burned out.

I'm now back to the old halogens and plan on replacing the whole setup. I've also learned to never use an LED on a halogen driver unit!

how long have the dimmable ones been that cheap? i hadn't seen those when i got mine before xmas, but they look like a non-standard shape and wouldn't fit into my sockets as they're shaped specifically to fit the halogen shape GU10 bulbs, so a lot of the elongated LED GU10's won't fit in my sockets.

can't find any of the Osram DuLED's anywhere except amazon though, would love to find them cheaper somewhere.

Dunno, but core pro appear to be slightly cheaper. I'm holding out for a well priced 6w (50w equivalent) Master. Still commanding silly money ATM.

powerstation

While shopping for LED's I noticed the Philips Master GU10's were dimmable while the CorePro spots weren't. There were other smaller differences with the Master range having a slightly wider beam angle and estimated lifespan.

I now have 3 of these Philips GU10 CorePro's 2W spots in a fitting. While the beam angle is slightly narrower compared to the halogens, I find the light is pleasant and not as glaring, these bulbs are cool to touch even after they've been on for hours.

Master led also have 5 year warranty and much higher switching cycles so for example in a bathroom or pir activated fixture might be debatably/theoretically worth the extra money.

Those are only 120lm nowhere near 35w for £4.99, I think the ikea ledare is a better bet at 200lm €5 or the 250lm integral ones mentioned here before at €5.90.

The description sums it up: "Warm White (2700-3500K)" thats a vast range! I found the colour temperature on the sample of these I receive to be around 3200k / 3300k which is too cold for the average irish punter and with too much green phosphor in the resin giving a green cast like the old cfls.

This is my take on LED prices

http://www.buyincoins.com/?r=category/index&cid=157&keyword=beads
yes that's just for the component and yes the ratings might be a little off, but it gives an indication of how much prices should be dropping in the near future


They also do bulbs but I'm not so sure I'd trust mains voltage stuff from them.

MR16 stuff - but I'd be wary of using them with an unregulated transformer

I still don't think that we will see the drop that people will expect.

company X sells 10 people 1 lamp each, each lamp last 2 years after 10 years they've sold 50 lamps.

if company x moves to LED then this is what happens
company X sells 10 people 1 lamp each, each lamp last 10 years after 10 years they've sold 10 lamps.

Longer lasting lamps reduce the market significantly. Companies like to keep profit coming in, with a reduced market the only way to do is to keep the mark up high.

could be a simplistic look at the market that's flawed, but that's the way i see it.

Over the last 300 years in all societies people spend about 0.72% of GDP on lighting

http://www.sandia.gov/~jytsao/tsao_jy_2010_04_app_for_light_LEUKOS.pdf

The World’s Appetite for Light: Empirical Data
and Trends Spanning Three Centuries and Six
Continents
...
The data span a wide range
(three centuries, six continents, five lighting technologies, and five
orders of magnitude), and are consistent with a linear variation of per capita consumption of light with the ratio between per-capita gross
domestic product and ownership cost of light. No empirical evidence is
found for a saturation in per-capita consumption of light, even in
contemporary developed nations. Finally, we extrapolate to the world
in 2005, and find that 0.72 percent ($437B/year) of world gross
domestic product and 6.5 percent (29.5 Quads/year) of world primary
energy was used to produce 130 Plmh/year of artificial light.
...
We conclude that, to a very good approximation, people in nations over diverse
temporal, geographic, technological and economic circumstances
have expended 0.39 percent to 1.30 percent (with a best fit value of 0.72 percent) of their
gdp on light.
We also conclude that the income elasticity (at constant price)
and the price elasticity (at constant income) of the demand for light are both
unity or nearly unity.

probably a silly question, but what would it take to turn one of the LED components into a functioning LED light?

could someone with electronics knowledge put everything together or is there a lot going on inside the bulb other than transforming the mains supply into the right watts/amps to light up the LED?

I was just wondering as i saw this 100w LED: http://www.buyincoins.com/item/38400.html

and wondered if someone with a bit of electronics experience (i.e. not me ) could take something like a traditional 100W halogen outside PIR spotlight and do the required work to replace the halogen bulb with the LED one or (and I suspect there probably is) is there a lot more involved than just supplying the prerequisite wattage to an LED?

I'm obviously not going to try it, I definitely don't have the skills (or i wouldn't be asking the question) i'm just a curious sort of person.

I'm also wondering how much brighter a 100W LED would be than a 100W halogen. :eek:

I know, but they are very expensive compared to a halogen light plus the cost of the LED part(s) to convert one.

Also, I'm not looking for one, i'm just curious about the workings of them.

looking at some more video's of the 100W LED's, you need a heatsink about the size of a brick to properly cool it, so it wouldn't be all that practical.

Yeah - I was going to say heat dissipation was the big problem. I have an LED on in the garage waiting to get fitted. Buckleys in Santry were doing them for €10 before Christmas. Not very high wattage (10W I think), but my old man bought 2 to replace a 500W halogen and is very happy.

I'm a electronic Engineer, what your asking is fairly basic and quite doable. but there's plenty of products out there, so its not really worth while doing.
Your really just looking at supplying a constant current, heat dissipation. you'd need another engineer/designed to design the casing to ensure that you are maximising the light out put.

the only downside with the 100W LED is any time you turn it on people will think you're getting raptured! :pac:

probably a silly question, but what would it take to turn one of the LED components into a functioning LED light?

you'd need a power supply matched to the LED usually a constant currant one

it says DC Forward Voltage(VF): 30~34Vdc

so 100W would be about 3A

if you are feeling brave and know about heat sinks and thermal runaway then http://www.buyincoins.com/item/9004.html or http://www.buyincoins.com/item/11860.html but they'd be more suitable for lower wattage LED's and light output might change as they warm up

Generally you'd use these to drive LED's - but they are lower ratings and I woudn't recomend messing with mains equipment

on Amazon Good price for the Master

If you look at "new from" option there 7 pounds a pop. I use Parcel motel so Amazon UK postage is easy.

Good price, cheers

I see a tenpack deivered from amazon themselves for not much more. Handier for issues/returns.

BTW would 5W be overkill for a kitchen with 8 spots? Think the 4w at 59.99 might be better bet...
