    Still love the light output and colour rendering of the CFL bulbs I have to say (once they have warmed up) - so now I have swapped out 3x60w candles (180watt) for 3x 11wCFL (33w) - not as saving as the LED 3x 5w (15w), but just the right brightness and nice warm white colour

    A decent LED, like the IKEA ones, would have a colour rendering just as good, if not better then a CFL.

    thats good - what wattage LED would you need to equal an 11w CFL or 60w Incandescent then? - we have no IKEA down in my neck of the woods , but we have a pretty good trade and retail electrical place called Cliffords in Sligo and they had a pretty good display of LED bulbs on display.... pricey though I bet. not as cheap as the CFL's I bought at €2.29 each or €1.49 DEALZ ones

    I have several Osram LEDs that I picked up cheaply in Tesco last year when they were selling them off. The 6W bulbs are the equivalent of 40W incandescent and the 10W bulbs the equivalent of 60W incaldescent.

    Sunlight / incandescents have a continuous spectrum with no wavelength gapss

    Being pedantic there's no such thing as a white LED or white CFL.

    The colour depends on the phosphors used. Warm vs. cool is a user preference. Lampshades change colours too. But nowadays if you spend a bit more you can get RGB LED and choose your own colours.

    Surprising that - so a 10watt LED = 60w ... but a 11watt CFL also equals 60w too - mind you on paper the LED should last longer (lifetime) and have no harmful mercury as the CFL has - but not saving on wattage then

    An 11W CFL is really the equivalent of a 55W incandescent but I think even that's a bit optimistic, especially as CFLs loose brightness over their working lives. There's no doubt that over the coming years LEDs will become even more efficient.

    My Osrams are dimmable too which is something that's tricky to do with CFLs and doesn't produce the most pleasing results.

    Cool, I mean quite honest though when bringing out these LED lights they should have made them so they were all dimmable - wonder how many people have put them into a fitting with a dimmer switch either not reading or taking notice of what it said on the box. - With incandescant bulbs home consumers would have been in no doubt and could have used with or without a dimmer. no thinking even needed. so when they brought out 'replacements' (such as CFL or LED) at the very least they should have been on the market as being able to be dimmable as standard!

    The problem is, even with dimmable LED's, they won't normally work properly with old fashioned dimmers designed for incandescent bulbs.

    That isn't the LED's fault, it is because the old dimmers simply weren't designed to go so far down in voltage as LED's and CFL's go.

    It isn't just a case is the LED dimmable or not, it is also the case of if your dimmer switch in a modern low voltage supporting one too. And if not, then you need to replace the dimmer switch too.

    As to why they don't make all LED's dimmable, it is because it requires extra circuitry and electronics and thus extra cost. The reality is the majority of light switches aren't dimmable, so why make people pay more for something they don't need?

    ah right, didnt realise that some of the dimmable ones would not work properly on old dimmers. makes sense i suppose

    The price is attractive, how about the quality?

    They were doing these in lidl for €10 lately. Friend got one, on the instructions is said they aren't designed to be in use as a regular light bulb, up just occasional use - or something that suggested they wouldn't last too long.

    I got this RGB remote control LED Bulb last year from LIDL or ALDI (Cant remember which one) but look what happened when I was unscrewing it from the light fitting! - so dangerous, the (very thin) glass cracked and broke and I was hardly using any force! - could have shred my fingers or flying bit of glass could have gone into me eye! - would have been safer to use a plastic frosted cover me thinks.
