It's rubbish to those with proper eyesight.

Awww did I offend the blind fool?

You can get LED lamps for any colour temperature these days even down to

2700K although I have had some marked 2700 that were more like 3500. You can't complain about the brightness of the latest generation - they leave CFLs in the dark for lumens per watt now and start instantly at full brightness which is very useful on stairs.

I do believe the best way to get good colour rendition from white led's, is to make the white up from RGB led's. I believe the white led's produce ultra violet light from the die, then convert it to white using a phosphor lens or something, but either a single RGB led, or a selection of individual red, green and blue led's close together seem to produce a much nicer white, and you can easilly adjust it to your taste of white by varying the brightness of the individual colours current.

Butchers have special fluorotubes withe extra red to make meat look better. Ordinary fluoro tube phosphors the light with the higher green content makes the meat look past its best and unappetising.

It is actually a hard blue light and the broadband phosphor is amber yellow bordering on red. The final result isn't too bad these days once there is a diffuser around it. How much red determines the effective colour temperature. Early ones tended to have obvious coloured fringes at edge of beam if they were used in water clear packaging.

Very much more expensive to do and you have a nightmare mixing the colours properly in the beam. The new generation of stage spotlights are done this way and can mix any colour to order. White ones are still a lot cheaper and brighter if you only want pure white light though.

They do exist in consumer products too but are generally more expensive and less powerful than the highly optimised warm white LEDs.

(not an endorsement I have never tried one)

[Gefreiter Krueger]

Indeed. I have both here. But much prefer the 6500K.

Agreed.

I've always found R+G+B to work out cheaper, using Rapid prices.

just use 2 stage diffusion.

its easy to add a control to dial any colour.

Finished products are, due to size of market.

Oh i know that, it's just that this fridge had horrid blue/white LEDs which really did make the fridge contents look unappetising. I wouldn't buy a fridge with LED lighting without out checking the colour first.

I only mentioned as others might also like to check first.

Well unless they fitted blue LEDs which I very much doubt, then the food would be the correct colour with a (true) white LED.
