For a limited time, we are offering our new stock of DIY LED products at a discount price. Our normal prices are still some of the most competitive on the net, but during the sale, you can cash in on extra savings.

Currently on the site, we have Cree XR-E Q5 (WG bin) cool whites, and royal blues, mounted, for the low price of $6.29 each. We also have genuine Cree optics in 40, 60 and 80 degree angles for $1.19 each.

New to our product lineup that will be shipping soon is our new adhesive thermal pad. These pads are custom made for use to fit the standard 20mm hex pcb for true peel and stick application of your LEDs to the heatsink. With a 5mil thickness, they provide a great, easy to use fastening solution with minimal thermal resistance. We are introducing these at $0.49 per pad.

All sale items can be found here

Stay tuned for more products to be added to our lineup of DIY components.

Is the 38PAR lamp comparable to any Halide?

Depends on the height that the lamp is mounted above the water. Greater the height, lower the PAR. Changing the height is needed to get the coverage required. So basically, it's going to depend on the tank you are looking to light with them. Can this replace a MH lamp? Sure.

OOO. mes am interested. i want it for a frag tank...

15w Cree Lamp

would this have the same power as a 70 watt MH ?

And greater, depending on the height it is mounted above the tank.

Love the "lighting bt Evil" section. now time to come out with several options for drivers and you're set. any time frame when/if drivers will be offered? what about 555/556 timers for the meanwells?
if the build im planning for works out, i'm going to need 28 meanwell drivers and 352 total LEDs!

how far should the light be from the water to get the best par ? If it was close enough could it be a 150 watt MH?

We have Buckpucks on order and should be showing up in the store soon. We also have the basic 110v AC 700mA fixed output driver up on the site too, but not in the "Lighting By Evil" section. It's a really basic driver, but it's so cheap (110v AC input, 6 LEDs max at 700mA). We are debating on other drivers, like the Meanwells, but haven't decided yet. I may have some other options in the near future. Liek I said in my other posts regarding my tenure at Nanocustoms, I have lots of good ideas that I can now see to completion.



All depends on what you are looking to set up. Are you looking to do a DIY setup, or use the PAR38 lamps? Your question was a little vague in that regard. Shoot me a PM and we can continue this conversation. This thread isn't the best place for it.

are the RB up to 1000ma?

You should have no problems running the Royal Blues at 1A.

With the heatsinks that we typically run, 1000mA on the royals is fine. The die temperature stays pretty low.

do you have any pic of what the 20K would look like, im wondering if it would be to much blue for me. Thanks guys

I'll see what I can do. Best comparison I can make is it's about the same color temp as a Phoenix 14K MH (which is more blue than 90% of all 14K bulbs)

I have a 72 Gallon Bow Front. What is the equivalent lighting for the PAR38 lamp on that size tank. If I get like 2-4 of em.

2-4 certainly is not going to be enough for a tank that size. You would need at a minimum 6, but would be better with 8.

Would the thermal pad be sufficient thermally to run 24 LEDs on a 7x14 heatsink Using typical DIY methods?

Certainly would.

So i don't need to drill my heat sink? This seems too easy...

I wouldn't be selling them if they didn't work. Like I said before, it's not as good as bolting them down, but it's still a good alternative. It's on par with thermal epoxy in terms of performance, just without the mess.

What downside is there to the pads vs bolting them down. Is there just less thermal conductance? I'm hoping to do another LED build if there is ever another group buy and drilling/tapping the heatsink was the worst part of it all. I don't have the patience for it and broke a number of tapping bits in the beginning . I know I could do it right now that I've had practice but avoiding that would still be amazing.

Edit: I guess the nanotuners price is essentially the same as the last group buy for the LEDS. How long do you think those prices will last?

The pads are considerably less labor for a minimal loss in thermal performance. There are some extra step required other than just peel and stick, but it's still far easier than drilling and tapping.

As far as prices, they aren't as good as we got for the group buy, but they are some of the best on the net right now. We are trying to keep those prices for as long as possible.

Ok, as always thanks for the information!! Hopefully the new build will be a bit more presentable

NVM ordering.

Meanwell drivers coming soon.

sweet!

If I were to buy two PAR 38 15w Cree lights, would that be sufficient to keep corals in a 55 gallon tank?

Not really. A 4ft long tank like that will need a lot of lamps to provide good coverage. Expect to use 5-6 of them. I'm using 4 on a 40B (36" long).

okay, cool. Thanks

Make sure you don't miss out on the last of the Meanwell drivers. We bought out the last of the stock and it will be quite a while before more become available again in the US.
