Optic lenses are used to focus the light beam... 90 degree being most common...

60 lenses are prone to cause beams so they need to be mixed in with other optics ( options you have with DIY kits )

My tank is 30"L x 12"w x 18" deep. I was thinking that the tank only being 12" wide the optics would help with the overspill of light and with them being dimmable i could keep them dialed down not to burn the corals.

Or am i wrong and should i go with the 120*?

Sorry to say but the big drawback with black boxes is customization.
90 degree optics in that tank will cause spotlight effect on sand bed
Over spill is remedied by putting outer LEDs at an angle to cast away from the glass...

You should be fine with the 120 degree lens...

Ianwraab how legit do you feel the warranty is on the unit from aliexpress the 120 watt one with 55x3 watt leds the one that 175? Is there solid proof they will really warranty it for the 3 full years they claim?

I'd say yes... I was very impressed with the service I received... Compared to the other china companies I poke with alibaba.com is absolutely phenomenal..

Anyone can lie...
Bestbuy screwed me on my extended warranty on my laptop... You think they would be the most reliable....

I bought 2last night and I'm a bit tight with my money so I'd say...
Yes they will do as promised....

Sam Chen at alibaba.com is the man!

Travis1787 · 05/04/2012, 07:48 AM

Travis1787 · 05/04/2012, 10:17 AM

Contact Sam outside this thread... sales02@ledgrowlights.c
We are a bit off topic...

Anyone got pictures of a tank that has been running black box LEDs for more than 6 months.

Sorry, I am a stupid newb mixing terms.

I should have said do I need the 90 degree lenses over a 24x24x20 cube?

Can I just order the same one as you? Or do I need 120 degree lenses.

Thanks

Link didn't work but I am setting up the 24x24x24 cube that is going to be all SPS. So I am guessing the same one would be fine?

Got the idea on optical and the only thing I worry about is that they look too blue. it seems like a lot of these unit's from china are very blue? the white color temp is saying 18k?

Travis1787 · 05/04/2012, 05:39 PM

Ok so what are the par readings or lms on these units? Don't see them anywhere ... Also which optics are better?
