Hi I have them in bathrooms and kitchen, they are excellent color, light output and spread. I have them in bout a year now, with heavy usage on three particular bulbs and still going strong. Happy customer!

Do not generate any heat???? You're having a laugh.

How much heat would they generate in comparison to a "normal" bulb of the same illumination ?
10% ? (I am just guessing)

Regular incandescent bulbs can lose up to 95% of their energy as heat, LEDs can lose 85% as heat, but then you're talking significantly less input energy (5W versus 60W say) as LEDs also produce more light in the visible spectrum.

Look at any of the higher power LED bulbs and you'll see they have heat sinks/fins built into the package to transfer heat away from the junction, as increased heat there can have a significant affect on the light output and lifespan of the fitting.

If an LED bulb is not producing heat, you can be 100% sure it's not producing any light.

LEDs produce a lot of heat. Why do you think they have huge cooling fins on them? You want to have a look at some of the 4x4 LED lights and the array of cooling fins on them!

Joined to post that misinformation, let me guess, you sell LED lighting!

Sorry for the thread hijack... I'm pretty sure I know the answer/sentiment..

Just using here as a sounding board...

New build house, last phase of an estate. House is at first fix stage, plumbing done, electrical to kick off. We're looking to get dimmable LED (Standard voltage) downlighters installed in various rooms. Between 20 and 30 downlighters total throughout the house.

The electrician is coming back with a price that is averaging in the €90 per downlighter range. Note: It's a passive A rated house a number of these downlighter fittings need to be airtight but I understand that's done with a "tophat" which costs circa €7/€8 per light.

Thoughts... I have my own but just interested to get other views.

I have just today replaced the last three gu10 down lighters with led bulbs. Only have in total 8 down lighters in the house and if I was starting to build again I wouldn't put one in ! I would redesign and put way more effort thought into the lighting scheme. A beautiful room during day can be ruined at night by bad lighting. IMO down lighters do nothing to set a mood for a room. If you are going to spend that much on one down lighter why not spend that budget on nice wall ceiling or table lamps? Only a thought.

There is a voucher to get 4 for the price of 3 so 160 bulbs for £140.

Anyone know about the wiring of an led driver, on checking the lights fittings to see if earth cable is connected I noticed that the driver is wired the wrong way, the brown and blue wires are reversed, so do I connect brown to blue at the main power cable or just leave as is.

And will it do the led driver any harm if I leave as it is, as if I didn't see it.

Out of a batch of ten of 10w outdoor led lamps four are wired wrong.

Thx hatchman, appreciate the feedback... we negotiated and arrived at a better number... stiller higher than I'd like but a little closer to reality. In our case we'll have a combination of pendent & downlighters with both in dimmers. For living room etc. we'll probably also have a lamp or two so just use whatever depending on the mood/people over/movie etc.

i bought a lamp for my daughters bedroom - its one of the weirdest plugs Ive ever seen before but i guess thats IKea shopping for EU.
Heres is the plug


here is its connection:


Its making a noise - like a humming or crackling - i wouldn't call it static as its too loud but thats what I'd like to know - what the hell is the noise,
The bulb is a Philips 20Watt halogen - is the halogen the problem or is it something else.

If anyone can offer some advise Id appreciate it.Thanks

evosteo

With a connection like that it looks like a combination power adapter/transformer. It prob the transformer buzzin. No problem

Bought some auraglow dimmable led bulbs below on Amazon. Very impressed this far. Very bright on highest setting and can be dimmed through a good range of brightness.

Pricey though.

Apple used to have connectors kinda like that

hmm i hope you dont try and plug in a phono lead.

Help needed please.

We've previously kitted out out house with the highest lumen, known brand, GU10 spots we could find at the time.
These were the Philips GU10 Master 8W, 2700K 40deg, 430 lumen (about €25 a bulb).
I put in a couple of these in my brother's kitchen a year ago. I now need 4 more to finish his kitchen but Eurosales say they're obsolete.
I'm not going to pay £35 a bulb on Amazon.
But I can't seem to find any high wattage/lumen GU10 Philips bulbs.

Does anyone have any recommendations? They don't have to be dimmable. I'd like to keep high lumens, with a 40 deg spread to match what is there already. They don't have to be Philips, but since I don't expect them to be cheap, I would prefer a reputable brand. Tx.

I think the highest lumen output from reasonably priced Philips lamps 5W 350 lumens for a Philips core led.

Did those Philips lamps at 25 euro not have a 5 or 10 year guarantee? The shipsbyou bought it in should replace it with like for like or equivalent for free

The Master LEDs are all still ok. Of the 15 I bought all 15 are still going well 2 years later.

In my brother's kitchen there were 6 halogen spots.
I replaced 2 of them a year ago when the bulb/trafo blew, but we left the remaining 4 until he had the spare cash to replace them.
So it's the 4 old halogens I'd like to swap out.

Are the 6W Megaman's worth considering? I'd trade a few degrees of spread for a few more lumen.

Woodies are currently doing 3 for 2 on all bulbs... although my local one is pretty cleared out!

They have Luceco LED GU10 bulbs, pack of 2 5W dimmable for €16.
(They're like these on amazon)

Has anyone ever used this brand before? Just wondering, because I've done a forum search and can't find them mentioned and it's not a brand I'm familiar with.

Anyone know of any deals on GU10 Im guessing 5w and upwards and dimmable ?
I would need approx. 25 of them..

Hi, One of my T4 bulbs has blown in my under cabinet lighting and I am looking to change to an LED type bulb. What is the best option? I know T4's don't come in LED and they have different lengths depending on makers. Would changing to T5 fittings be worth it? Is there other options? I have 4 bulbs all wired back to a single switch if that makes a difference. 2 bulbs are 16w and 2 are 30w. All bulbs are robus. Any info would be great. Thanks.

I replaced our T4s with LED Strip (5050 SMDs although I probably only needed the 3528s)

I got these from Lightrabbit. They are bright. I got the cool white ones. I think the COB LEDs are better than the SMD's for brightness and they are dimmable. There are promo codes available for Lightrabbit so might not be too expensive when buying a large amount.

Something like this?
How many LED's where needed for each bulb you replaced? Would 500mm of this LED strip replace a 500mm florescent tube for brightness or would you require a longer strip?
