CFL - kelvin rating

**skip** · 05-09-2007, 06:41 AM

I'm using 25 watt CFL's on my seedlings. I can't find the kelvin rating of them anywhere - either on the packaging or on the bulbs themselves. The shop where I bought is too far to return at the moment cause I'm busy, and I couldn't find a website for the bulb manufacturer. So...I wondered if anyone knows of another way to work it out. Is the lumen rating perhaps related to the kelvin rating? My bulbs have lumen rating of 1300.

The lights look pretty bright so I'm hoping they are daylight or cool, but the light from them also looks a bit kindof yellowish to me and I'm worrying that they are warm. Any help appreciated.

your guess is as good as mine. if they look white, then they will be 6400k, yellow and they will be 2700k. look at the glow they give rather than at the actual bulb..

Thanks morp. I'll try to work it out. The packaging seems to have every piece of possible info apart from the kelvin. When I bought them I didn't know then what I know now about the warm / cool veg / flower split. Manufacturer of these bulbs is Lexman.
