I want to conduct an experiment but I need to find proper CCFL tubes. They need to hit certain peak wavelengths. So far the only directly targeted one of four wavelengths I need that I have found is an Actinic CCFL. That handles 420nm, now I need something for 460, 630, and 660.
Hopefully they're all the same 3.6W tube at 300mm.
This might lead to something not as long-lived as the LED bulb but I won't need to worry about heat-induced failure, nor cooling. I'm not trying for massive plants, this will be more for multi-stack NFT systems.
