    Dallas dont they give a tight beam ? The reason I am considering them is I suck at soldering

    There we go, rather buy from General Lamps, you can spec the LEDs as you want.

    Oh and if you look at my latest pics, the tanks been running for 3 months so they can definately sustain corals :)

    For reference, each bulb is evidently as powerful PAR wise as a 150w MH. And after using them I tend to agree. They are pretty potent.

    I used standard ceramic E27 sockets that you get from any electrical outlet and connected them to the hood via 2 screws each. I then used some trunking to neaten things up. Took maybe a day to get it all together. I know how to solder but I liked this concept since I could chnage out teh bulbs very easily and I didnt need ballasts. It was a real simple DIY.

    My units have the 90 degree lenses so no not really, you only really notice the beam if you stir up the substrate. I would supplement with T5's though like I have done, it just seems to fill in the gaps a bit more than if you run them by themselves. That and the white from these LEDs are quite white, between 8 - 10k I would say, so you could use the T5's for actinics, which aesthetically, balanced out the tank a lot more.

    Yeah fly I would love to use these on a nano, where did you get them in the end, and for how much? I have a bunch of contacts for LED globes of this fitting, but none of them know the full specs! :(
