Why does the colour temp vary so much on bulbs. I bought some 2700K LED from Ikea and really liked how warm they are. The flouro in my kitchen later went out and I bought a couple of 2700k flouro T5 bulbs and they are yellow and hideous, even after being left on for an hour.
I am a photographer and like to think I understand white Balance but I don't get why these vary so much.
You definitely don't want fluro lights in your kitchen, talk about ugly harsh light, tear that crap out and install some LED's, then they'll be the same temp.
WTF flouros are a soft light. I'm not about to pay $500+ to install a bunch of LEDS just because they are trendy at the moment and they might save a few bucks on electricity.
You're insane if you think fluro's are soft, you're insane if you think LED's cost that much, you're insane if you think they're 'trendy', and you're insane if you think the electricity difference between types of lights are significant enough to take into account. Warn me next time before I comment on a crazy person's thread ok? Ridiculous.
Installed by a qualified sparky they cost around $120 each. I would need 4 to cover my kitchen.
" Soft light is when a light source is large relative to the subject; hard light is when the light source is small relative to the subject. " https://en.wikipedia.org/wiki/Hard_and_soft_light
Flouros are a large light source, they are soft, that is not my opinion that is a fact! Google up soft light kits a lot of them are flouro (there is many other types also)
you're insane if you think the electricity difference between types of lights are significant enough to take into account.
That's exactly what I said the diference in cost of electricty is not significant enough to be a factor.
Next time an ignorant person who is talking out there ass comments on my thread warn me.
2700k is very warm. I have 5500k in my office to mimic daylight and 4500k in most areas. I rejected a large shipment of 4500k that measured close to 4000k because I could eyeball how yellow they were.
2700K LEDs != 2700K Fluros. The very nature of the light is different, so even at the same colour, the way your eyes perceive it will be very different.
Colour temperature can be wildly different between lights sources that use different methods for generating light e.g florescent lamps use UV light reacting with a phosphorous coating inside the glass tube to generate light so overall efficiency of light rendered per watt of can vary.
Another consideration is the lamp housing , if a diffuser or coloured lamp enclosure / shade is used it can give the lamp a very different look.!
There's enough variation between the different companies even if it's only 100-150 kelvin, so if you want a uniform colour temperature for the lighting in your home you will be best to stick with one brand, and ideally, the same batch and bulb size / type.
