Lighting question.....

[QuantumCranker]

Has any one ever tried these http://www.servicelighting.com/catalog_product.cfm?prod=TC28946&link_p=TCP-light-bulb-28946
With a good reflector, how do you think these would do for a planted tank?

I've read some reviews by people who have used them and, as a replacement for an incandescent bulb, they work wonders. Because of their twisted design they are not as efficient as a straight CF lamp of comparable wattage because you get a lot of strike-back, but they are still far superior to incandescent and work great in tight spaces

they work great for low light tanks, like 5-15 gallon tanks...which is where you usually find incandescent fixtures in the hoods.

the U shaped bulbs are better than the spirals in terms of light lost due to shape and restrike.
