Alternative energy saving light bulbs - warmer glow?

Have a shufti here to get an idea of the different colour temperatures of light http://www.thelightbulb.co.uk/resources/colour_temperature

I tend to avoid the blue/daylight variants; some say that these are bad for your eyes. :eek::eek:

I'm not a fan of the 'filament' LED bulbs; they are something designed to look like something they're not (ie incandescent bulbs).

I did order one a while ago, and it arrived with a filament broken. I asked for a replacement, which was sent, and it was the same. The third one was OK; however, I wouldn't have another and wonder if they are more fragile than a simple LED. And, if they were inside a lampshade, you wouldn't see the 'quaint' effect anyhow.

IN which case doe sit matter what they physically look like?

I bought a few warm white LEDs 4 watts from Poundland (small screw ) for the main living room as we have 10 holders to fill. The other energy bulbs were always blowing every two minutes ! its a lie that they last 6 years..Maybe if they are never switched on and off they will last that long but switching CFLs on and off shortens their life.
So far the Poundland cheapies ( a quid each ) have lasted over 9 months..the two light cluster of 5 each only consume 40 watts an hour total making it only 0.4p an hour to run all 10 lights..amazing value. LEDs are the future for everyone.
Warm white are suitable for living rooms and the stark white LED s will be ok for kitchens and bathrooms.

But that's an old newspaper article about older research, all of which is about CFLs, not LEDs. More inaccurate use of the 'energy saving' terminology.

My son has issues with fighting and never sitting still, It was recommended to get daylight bulbs via a medical professional as they do not flicker so are supposed to be kinder on the eyes/environment. I have no idea if this is the case I never researched it but I like the light they give off so have kept with them.

All bulbs will flicker to some extent as they are fed from 50Hz alternating current. It tends to be more noticable with fluoresecent lamps, including CFLs.

Even incandescent lamps flicker but the thermal inertial of the filament makes it less noticeable

I'd doubt that the colour temperature makes any difference to the flicker effect

But it does!

I can't understand why anyone would buy an LED retro style filament type lamp with a quoted life of only 10,000 hours, when you can buy a standard type LED lamp e.g. here with a quoted life of 25,000 hours for a similar price. The filament type LED lamps do seem to be more delicate.

Notwithstanding, those Screwfix 'virtual filament' retro lamps are more efficient (A++) and come with a 3-year manufacturer's guarantee. :rotfl:
