Johnny,
Thanks for the info, I will contact you when I am ready to place the order. Just trying to sell a few other things first to offset the cost of these.

It's relatively simple actually...
The light output from the LED, is focused, magnified, dilluted, or narrowed by a lens. That lens, can also be called an optic.
The "degree" of output, is the amount of light angle coming from the lens.
For example, an LED with no reflector or lens... would be a 180°
An LED with a reflector, that has no lens or diffuser would be similar to this;
I hope that helps explain it a bit.An LED with a reflector, and a specific "angled" lens (for example a 120°) would be similar to this;

Johnny- how many units would i need for my 75gal? Dims are- 48long 15deep, 30high.
Just wondering if this enough for my tank measures 3 ft length 2 ft wide 2 ft depth.
How many is good for a 61 inch tank?
How many do you have lined up so far? I may be interested in 2 hopefully that could drop the price a bit. Thanks!
Lined up? Only 1
When the buyer has dropped off the money, I consider it "lined up". There's lots of people interested, but that doesn't help the cost.
It takes 5 or more to get a discount.
