At 3" you'll get some spotlighting with lenses, so for your FOWLR tank you might want to consider not using any lenses. Take a look at our kits,...
Hi there, For a FOWLR tank that size I'd go with about 30 LEDs or so, and for Reef I'd go with about 60-72 LEDs depending on what you'll keep...
Hello to all our friends at 3Reef, Just wanted to let everyone know that we're having a one-day sale tomorrow for Christmas! The sale starts at...
Hi, AC adapters, come in two main varieties. The first is regulated (switched), the second is unregulated. They behave differently electrically....
Sometime in the near future we'll be able to offer them with a 40 degree lens, but that's probably as wide as we can go for the foreseeable future....
It means that a lens won't fit on top of the connector, so you can't use a secondary lens (the traditional 40, 60 or 80 degree lenses) on them. The...
Yup, just fit them around the LED (you'll have to match up the + and - on the connector to the + and - on the star pcb), screw it down, and insert...
Hi Everyone, We constantly get inquiries from people who would like to DIY their own lights but are uncomfortable with the amount of soldering that...
what's your budget?
You can go from 3-14 LEDs on the Meanwell LPC-35-700 (or LPC-60-1050 if you're using XP-G's). To figure this out, take the minimum voltage of the...
Hi there, If you want to test the LEDs individually many times people wire together two AA batteries, which should give you enough juice to power...
Sorry this is so late, for some reason I never got the notification. At any rate, I'd go with 3 of the PAR38's on a tank that size. 4 wouldn't be...
Sorry, nothing planned for the near future.
I'd say at least 1 more PAR38, if not more.
The 80 degree lenses should work just fine for your tank.
If it were just LPS and softies I'd say it would be enough light, but with the SPS that makes me a bit more nervous. However, since they're low...
Actually yes you can but you'll need a power source. If you attach a 10V power source (or something like a 9V wall wart) to the driver you'll get...
We get a ton of questions about using dimmable drivers, so here are a few more FAQ's to add onto the list: Q: I am trying to adjust the V...
If you're running XR-E's (or XP-E's) you should adjust the SVR2 knob down under 1A. This will ensure the LEDs never get more than 1A from the...
I don't think it's necessary if you're using the proper driver for your LEDs. For example, CREE XR-E LEDs can handle up to 1000mA max. Thus, we...
