I just received these powerful little LED’s. They are 5 watts each and run at about 1500mA each. I’ve hooked one up just to see it in action and it was blinding.
My plan it to hook up 8 of these LEDs over the tank for about 3500-4000 Lumens.
These LED’s go for about 11$ each at my favourite local electronics shop – I love this store and will continue to shop there (I bought my arduino Mega 2560 there) – but I got 10 of these little starboard LED’s for $6.03 Canadian, which included shipping and they arrived in about a month. I also purchased an LED driver for them, which cost about 9 dollars all in.
PS: I took this photo with a super old tablet that I’m using in lieu of my phone (which I lost on a bus coming home from an aquarium store). I figure the Renoir painting kind of compliments the blurry photo of the LEDs.
