Really cool light

Hope I'm not telling you things you already know, but GE puts out three flourescent lights that may be of interest to you.

They make a "Chroma 50", which approximates 5,000 degree Kelvin temperature, and recently, I found two others that are cooler, yet: The "Daylight" which has a temperature of 6,250, and the "Daylight Ultra" which is rated at 6,500 Kelvin.

I was using the 5,000 degree bulb, and liked it, but I bought a couple of the ultras and plugged them in beside the Chroma 50, and the difference, even by eye, is very noticeable. The light from the ultra is VERY COOL, as in temperature.

Cost for the ultra is around $5.50 and for the Chroma 50's is about $4.50.

BTW, this is not a commercial. I'm a retired guy, not a GE person.

I mention these bulbs because cool bulbs advertised in magazines are so high priced.

Kind of you to inform us. I've been paying much more than that.

The most important consideration when buying a fluorescent bulb is the CRI or the Color Rendering Index. 100 is the highest. Over 90 is considered good. Lumichrome bulbs are listed at 98 CRI, the highest for fluorescent bulbs. The temperature is 6500 degrees Kelvin. They are the closest to north light that I have seen. Maybe I'm just another dim bulb but I think you get what you pay for.

I recently bought a flourescent tube light. The store clerk noted that it is a full spectrum. Is there a listing somewhere that lists the CRI value of different brands, models, etc?

Do a search on Google and put in the name of your bulb and the letters "CRI" and it should come up. CRI is tends to be mentioned only by companies whose bulbs have been rated highly.
