I am selling the rapidled actinic kits I bought to install over my 75 which I am now downsizing away from. I bought 2 of the 48" dimmable actinic kits to install in a dual 150 hqi coralife fixture but now that I'm downsizing tanks I don't need these kits. I did pay the extra few bucks for the drilled and tapped heatsinks and did install the leds already and slightly modified the case on one of the drivers to figure out a way to install them in my halide fixture. These kits are brand new and have never had power to them. Included are as follows. 2-48" drilled and tapped heatsinks with the 48 Cree XT-E royal blue leds installed, 4 dimmable mean well eln-60-48d drivers, potentiometer, 12 volt power source for potentiometer, 2 power cords (I was gonna wire all 4 ballasts to 1 power cord for ease of use but do whatever you want I guess, lol), more thermal grease, screws, and washers in case you wanted to change a few of the leds for different colored ones, and an led tester. All together these kits cost me just about $400 with shipping and whatnot and I'm only asking $250 for all the led stuff and if you the halide fixture I'll throw it in for another $50. So $250 for the leds and $300 for leds and halide fixture.
