I just built a small LED fixture last weekend from stuff I got from
www.rapidled.com. They were great to deal with but a little expensive. I haven't started it up as I ran out of time and had to go on a business trip before I got to test for shorts.
I will be doing a big LED fixture to cover my 290 when I get it going and I would order from ETG as they will do any order over $50 and have a way better price. Plus you get XP-G's and XP-E's which are more efficient. I will have about 180 LED's over the tank as a plan right now.
PM me if you want info on contact ETG. I can also give you a link to get meanwell's at a reasonable price. You want to use the ELN 60-48D as it's dimmable and can be controlled by an RKE, APEX or Profilux if you get back into a controller.
Try
www.heatsinkusa.com if you want to get some heatsinks. Though shipping can be ugly. If you find a canadian source for Heatsinks then please let me know as i haven't found any.
