Has anyone used a 40w Ultra Daylight fluorescent for their CP's? I had to try it today, since I upgraded my terrarium to 4 bulbs instead of 2. They are rated at: 3050 initial Lumens, 6500 color temperature, and a CRI of 75. Oh course the CRI is a bit lower than a lot of grow lights out there, but that is to be expected due to the high temp level from what I learned here in the posts.

Now my 50 gallon terrarium tank is powered by:
1x 40w GE plant and aquarium
2x 40w GE choma50's
1x 40w GE Ultra Daylight
and its completely surrounded by mylar! Hope it all pans out for me.
