I was in a LFS today peddling some plants when I saw a display of what looked like fluorescent tubes. They were the size of T12's, and had two pins on the ends, but they were solid white on top and had a strip of tightly spaced LEDs running the whole length. The manager (owner, I think) said he makes them, and he has switched all of his tanks. They had a display set up with the same size CFs, T5's, T12s, and the LEDs with devices that registered how many amps they were drawing, and the LEDs used one quarter of the CFs. They don't need a reflector because they only shine down. He said if I go buy a cheap shop-type fixture they will wire it (basically they remove the ballast and wire direct to the bulb pins). A 48" strip put out the equiv. of 80 watts, cost $129.00, and lasted 40000 hours. They can also be dropped with no damage (no glass) and you can touch them (very little heat).
Anyone using something like this?
