>Where do you find 13w 3500k bulbs?Where do you find color temperature listed?

Lowe's?

You can find these bulbs on line as well. But experiment.

One thing I've found since I wrote that article is that these bulbs lose both their color temperature and overall lumens over their life. I don't think I'll wait the 5 years for them to burn out before I replace them.

I've also noticed they grow warmer and brighter as they warm up.

I really like using the diffusers, BTW. I've installed them on more of my lights. Also keeps the dust off the bulbs, which probably could reduce lumens in shops with power tools fairly significantly.

>I noticed a difference in visibility and assumed it was my poor eyes.Now I believe it may be a difference in brightness.It has happened twice,both times after a period of time has elapsed busily creating joints. No lowes here.I'll have to check online.Or maybe I'll go to town and check the electricians supply place. Catching them is tricky for me tho since I only get to town on weekends.---Jack

>I always head down to the shop and turn on all my compact flo. lights a while before I need to work, they do take a while to reach full output. Switch them on and go make a pot of coffee/tea. :)

brightness degrades...

>Your observation of the brightness of these bulbs degrading over time is well known in the aquarium community where the life of the fish/coral/critters literally depends on the proper specturm and intensity of lighting. It's pretty amazing how much the output of these lights do degrade after a few years.

It's been years since I gave up my aquarium, but I seem to recall that 1 year was about the time period that was generally recommended for replacing bulbs.

Also the temperature seems to affect them

>When the shop is colder, they do not work as well as when it is warmer. At a minimum, they take longer to warm up. The older T12's are affected even more.
