my reef brite LEDs

How long are the power cords?

How long are the power cords?

Could a Reef Brite owner tell me how long the cord is from the light to the dimmer, then from the dimmer to the plug? Thanks.

Also, I heard these were 3 watt LEDs, true?

I don't know the cord length, the AC cord to the power supply is removable and you could buy longer ones if you look around.

I heard they are 3W LED with Cree internals and driven about 1.25w (30W/24 LEDs) some are loss in the driving electronics I am sure, If you have seen 1W LED moonlight you might know what to expect, except you get alot of them and with reflector optics.

niceee

I'm also wondering about the PAR of the fixtures too. Can someone who is able test and post? I would like to add one to my 4Xt5 fixture, but not if they don't provide that much. I saw PA says they are double to PAR of a blue plus, but how was that tested? Was there a reflector? Would like to see what those of you who aren't selling them come up with.
Strendo, can you post a comparison shot of the LEDs on with and without the t5s?
If these only put out 1.25 watts each but at 3 watt LEDs, anyone think about adding another drive to them?

 

[StrategicReef]

That was a T5 blue plus with a reflector.

If anyone is near my area with a PAR meter I am happy to have you come over and test the PAR.

IMO the current driven intensity is plenty bright enough without compromising lifespan and needing active cooling.

I also asked the manufacturer and they are planning on making a diming controller so dusk dawn transition will be seamless.

Has anyone used the blue/white ones?

I didn't know if the 100% blue led's would be too much with radiums.

tagging along looking for something on my son's 33 gallon tank.

Do you think 2 of these units could give off a shimmer effect similar to MH using only T5's? How intense are they? I'm using a 6 bulb Powermodule and really miss the shimmer I got with MH. I'm getting a bigger tank this spring and am thinking of swithching back to MH just for the shimmer alone. So could 2 of these units, one on each side of a 48" 6 bulb T5 fixture, give me some shimmer? Thanks for any help you can give.

according to the guys from Premium Aquatic, he noted that the Blue led only will not give you the shimmering effects if use together with T5s, however, the 50/50 or white only will.

I have a 48" Reefbrite. Really cool fixture, I had no idea you could adjust the output on them. I can't get a good pic of the color of the light, it's a lot less purple than this one:

How much spread are you getting with the fixture sitting on the tank like that ? Is it sitting in the middle partially blocking the PM ? There is supposed to be set screw to adjust the voltage on the transformer .

 

[StrategicReef]

I don't think there is alot of shimmer at least in my blue LEDs, the optics aren't made to give the sharp shimmer. There is abit of flickering but not the shimmer like a MH does.

 

[strendo]

The LED's are sitting at the end but I angle them into the tank. it gets pretty good spread, but 2 would be ideal if I had the room. Regarding the shimmer, you get it with only the LED's on, but not when the T5's are running.

Do you think that a 12'' white LED could be used just for lighting on a 33 gallon tank?

I think it would either work for a fish only or a very light limited tank.. for keeping xenia, dendros etc.

Thanks StrategicReef

Can these be mounted inside an aquatinics T5 fixture instead of outside?

It's an almost 2" thick bar and a full 48" long, even if you could you would be blocking your other light source quite a bit.

 

[steevareno2002]

i'll be replacing a T5 bulb with Led's. Maybe a 36" would work...Thanks

 

[StrategicReef]

my fixture is very narrow depth-wise, so it made alot of sense to mount it outside to give the proper coverage. Good luck on your retrofit.

Thanks for the pics! It helped me make up my mind to try them.
