My heatsinks arrived today. So that would be an overall awesome service from reefledlights.

I am glad you are happy with reefled. Bill has great service and quick shipping. If you email with any questions he will always answer and usually within the same day. have you figured how you will hang yours? I made stainless brackets, drilled and tapped the sink and will install them to the underside of the lid of my hood.

I already have an overhead beam, so I'll do if very close to what you have.

cant wait to see what the par says

Jeff,

Are you going to put a think acrylic or glass plate in front to protect from water splashes?

CoralBeauties · « **Reply #30 on:** July 15, 2010, 20:09:43 »

I have been running my current light for 2 months now without and shield. it is probably 12 inches off the water. My new light will be lowered by 2 inches but I dont plan on using any sheeting. i dont think that even at 10 inches I will have any problems with salt spray.

I have light envy!! I'm getting tired of my halides as soon as they turn on so does the central air for hours on end

. So what would the approximate cost be to light a standard 90? I would be looking for something as strong as 2x250 halides? Great looking light Jeff

CoralBeauties · « **Reply #32 on:** July 15, 2010, 21:47:54 »

unfortunately they arent cheap. You would probably be out close to $600 for 2 lights on the low side of being equal to 250 watt halides. that is measured with a lux meter. Not sure how the 24 leds would compare to the halides measured with a par meter. I removed my original light tonight and will start to add more leds tomorrow. In the end i will have 3 lights at 35 leds apiece. my hope it to be well above the 250 watt range.

ahhhhh. I'm seeing spots. Seriously, I'm playing with a string of 14 LED's and my variable power supply. I had to go get my sunglasses, so I could tune the voltage and current properly.

I just have a string of whites done, need to add the blue. A long way to go.

CoralBeauties · « **Reply #34 on:** July 17, 2010, 22:29:58 »

got the smaller heat sink mounted today and got the 35 leds working. The extra 11 leds really made a difference. Up against the 10k 250 watt halides they are visibly brighter. I am glad I went with the extra leds. Now to get the second light installed and come up the extra cash to purchase 36 more leds and i will be set.

WOW brighter then a 10k 250w. That is crazy bright. I am jealous.

CoralBeauties · « **Reply #36 on:** July 18, 2010, 08:30:17 »

When cyber is able to check it with the par meter then we will know how strong they really are. I would like to check a 10k bulb, 20k bulb and the leds with 24 leds on and then 35 leds on. One thing for sure they put out alot less heat then the halides.

Great to hear they are working well for you. I am happy with my led strip over my fray tank.

Wall_Tank · « **Reply #39 on:** July 20, 2010, 22:09:19 »

With Jeff as my inspiration.......here is my fixture. The green plugs will go to a separate power supply. With Whites on one circuit, Blues on another. The 7 wired down the middle will be teamed up with 7 from the other fixture. The 4 posts in the corners are acting as legs to protect the LED's......but after installation, there will be a thin acrylic sheet to protect from splashes and me hitting them. I don't have the optics on yet either.

Paul and Jeff, you're lights look awesome! Very well done guys.

HUNGER · « **Reply #41 on:** July 21, 2010, 08:21:59 »

looken good

Midwest Express · « **Reply #42 on:** July 21, 2010, 08:59:22 »

Very nice! I am def going to be moving forward on this since I am changing over to my 125 and I don't want to run all the MH lights. Looking good man! Can't wait to see how it all works out for you!

CoralBeauties · « **Reply #43 on:** July 21, 2010, 19:25:44 »

Paul your light turned out great. you probably got the newest cree blues. my first light has the older blues and my new light has the newer blues. Since I have them both running now you can see a slight difference between the two. The newer blues have a more violet color look to them.

Okay question... I'm not a very good d.i.y'er, so I'd need one of your help...

but it's about that time to replace the 2 bulbs in my PC fixture @ ~$100ish for both bulbs. I have a standard 65 gallon, and was curious if you thought I should put that $100 towards a LED setup?? I don't have a canopy or a hanging fixture, so not sure if I could use these, but just curious what you guys think.

Wall_Tank · « **Reply #45 on:** July 21, 2010, 21:27:50 »

Even if your not trying to reproduce the intensity of a Metal Halide light, then you may be able to do it cheaper than our setups. But with the 3w Cree LEDs, Your going to need some sort of heat sink and fan to cool it though.

You might look into some of the strip LED systems that are marketed to retro into old hoods. You may also just want to look at a T5 retro. T5 bulbs are much cheaper than PC. And you have a better selection.

Lights are finished, mounted on a test beam. I snapped these quickly, I have the brightness and the white balance messed up.

A bit messy, but the interface wiring. 4 drivers and the dimming control circuit from my Apex

HUNGER · « **Reply #47 on:** July 26, 2010, 22:38:02 »

brightness and the white balance messed up on the camra or the lights them self

That was in the 1st line of my message. I forgot to adjust, and was too lazy to fix. Part of it was because the lights were so bright. I'll retake them tonight, especially for you
