how many kelvin for this bulb?

Good question! All of my bulbs burned out before I was able to test this. Sorry! I would not recommend these bulbs to anyone!

The top-end (brightest) light is capped at 4500 lumens. On a Kelvin light scale it's a bluish-white light, which could be enough for your photography project. I've tried looking up a conversion scale, but those 2 units seem to be difficult to relate quantitatively, since it's not a bulb that you're measuring--high intensity LEDs instead. If you look up fluorescent bulbs, 4650 lumens delivers about 5000 Kelvin temperature light.

I do not know. I am not familiar with the UK bulb as I am located in the US.

These are 4100K, i had just found a 6PK for $14Triangle Bulbs T30033 - F13T5/CW, 13 Watt, T5, 4100K Cool White, 21" Straight Fluorescent Tube Light Bulb

Adam, Hydrofarm's website has it listed as "full spectrum daylight" - 6400 Kelvin.....double check to be sure...mine was doa and they were out of them so I went with another bulb.

I am sorry, but I can't answer your question. The bulbs are at my house in the north and I am in the south keeping warm.

they spec it in degrees kelvin. compared to other leds I've bought, they are more yellow, natural sunlight. The dispersal seems fairly even over the 120 degree pattern.

I don't know. I should research it as I don't care for the wattage. My bulb will probably last a long time because I don't like it. If you find one please post!

The description shows 3500Kelvin which is what the original bulb is. Incandescent lamps run around 2,700-3,300K and standard tubular fluorescent bulbs run around 5,000K.

http://anyray.us/default/catalogsearch/result/?q=A1700Y I went to this webpage. The little boxes they are in says nothing about the kelvin color temperature rating.

Are you asking for the Kelvin color or for the Lumens? Neither is listed on the package, but the light is warm white is probably around 4000K (not too warm). The lumens are low and equivalent to a 40W bulb.

According to the specs it depends upon which lamps you use but is 0 degrees F in most cases. The GE specification page for this ballast can be found here: http://genet.gelighting.com/LightProducts/Dispatcher?REQUEST=BALLASTSPECPAGE&PRODU;CTCODE=23675

I would definitely say between 5000K and 5500K, not any higher. They are a pure white color. I can see how they might be considered blue-ish after looking at yellow incandescent bulbs for so long. Look here --&gt; http://www.lightenergysource.com/kelvintemp.htm for why I say they are pure white and not blue-ish.

You know, a lot of people might think that this is a really stupid question, but lucky for you, I have the new K74Z bulb temperature analyzer, and after being energized for 15 minutes the bulb, in a room with an ambient average temperature of 76.5 Fahrenheit, reaches a temperature of 37.4 Kelvin.

Standard should work BUT the heat of the bulb melted the plastic...not good.

Hello,Unfortunately Vision X doesn't publish the kelvin rating of their light kits. I'm in the process of finding the answer and will get it to you as soon as I have it.Thank you,Ty DevereauxOffRoad Innovations

Can not help bought this for my son. You might try using Google by searching for 105w cfl. Will need to know the Kelvin temperature of the Bulb like 6500k or 5000k.
