I've been a lurker here for quite a while. This is my first post, so be kind.
Have you considered trying the LED strip lighting? I recently replaced my failing CF light with LED strips. I used samsung 5630 strips (I ordered rigid cased units, though this is not necessary). I was able to order them in cold white, 6000k to 7000k range. These cost me around $80 for 3 15w bars and a power adapter strong enough to push all of them, keep in mind that I overpaid quite a bit, these can be found on ebay and amazon for quite a bit cheaper. I then ordered a color changing strip with controller and power supply for around $25 (amazon). I cut it to fit inside my hood. The 5630's put out an estimated 1200 lumens for each bar. I started with just 2 of the 5630 bars, but quickly realized it was not equal to the 2 65w CF bulbs. I then added the 3rd bar and visually it appears to be pushing around the same amount of light. I can not say for sure that it is pushing enough light, yet, but considering I'm using less than 1/2 the power and it sure appears to be the same amount of light, i'm rather amazed. The LED strip was simply the color changing RGB 5050 "waterproof" kit that's all over amazon for $20 to $30. I can change the color from white to blue to green to red and nearly any shade in between. I rotated through the the different shades of blue for the one that makes my mushrooms glow the brightest. I use that color to simulate nighttime.
If I were to do it again, I probably would have just ordered all of it from ebay or amazon and would have got a full roll of 5630 (5 meters aka 16.4 feet)
