LED Fixture - cheap

[Dez]

These are the ones that I'm running on my full SPS tank now. I replaced 3 x 250W halides with 3 of these. It has been about 5 weeks and corals are still maintaining good colour and growth seems normal. At least I think they are these ones. I ordered mine from ebay and for 3 of them were $1000 shipped. Mine are black though. They are brandless.

really hmm, can you send me a pm of the seller on ebay that you had purchased the led from, i have bought led fixtures before but have thrown them out since it pretty much didn't grow anything, but they sure made the greens and orange glow in the tank

It was this seller:

http://cgi.ebay.ca/Aquarium-LED-90w-...#ht_958wt_1141

Except I bought the 120watt version. They have a 300 watt version as well.

Hope this helps. I'm going to give it 6 months of testing before I sell my halides.

reefkoi imports their own versions from china - http://www.evolutionledlight.com/. Warranty is completed out of the States.

reeffiltration - http://www.shop.reeffiltration.com/c...1?categoryId=5 - also sells similar speced units but they are higher output. Hes moved away from 1w LEDs and is now using 2w bridgelux. They are a better design but can not be dimmed either.

I'll be really interested in the review. Please.

Hey Mark,

First impressions is that it's got good build quality. It doesn't have heatsinks but seem to stay very cool. The fans are loud, but thank goodness I pretty much have a sealed canopy. Once you open the canopy that's all you hear are the fans. My tank temp has remained so consistent without the degree or two temp creep throughout the day.

It's been 5 weeks and several people have noted that there has been no change in my coral colours. Polyp extension and growth seem to be normal for my system. I have kept the same hours of lighting as my halides to keep it fair.

One thing I do miss is the "large" shimmer. These leds produce several "mini" shimmering effects in the water.

Like I said, I'll give it 6 months before selling my halides.

Only time will tell I guess. Hope this helps.

helps, thanks Dez.

they use a PCB board as the heat sink. I was asking my buddy about this as he lives in china and his company is producing a lot of LED products. that is why the fans are needed on these as the parts are all surface mount so they type of board they use has heat disapating propertys and then the fan cools the other side of the board.

I am actualy trying to design something with him, but the problem is to keep it cheep enough I would have to order a container load.. or part container load so I am waiting to find out how many units that entails before I go any further. I was hoping I could get 3 to 10 units at a reasonable price but it is soundling like I would have to buy a lot more than that. but who knows.. maybe I could flood the market with cheep high quality lights.. good thing I have a new job that pays real good

You realize these are cheap, cheap quality lights. I hope no one is putting these on anything deeper than 10in tanks. 1w LEDs, no optics aren't going to penetrate the water well enough to give you good growth.

Also I cant tell which LEDs they are using from the description but in most cases, these fixtures from China are using sub par cooling and LEDs. This will mean you will be replacing them every few years and you will be using more electricity than a standard CREE LED setup so in the long run they will cost you more than a higher quality setup within a couple years with less growth.

Please don't consider these anything close to equivalent to a AI Sol or CREE DIY fixture. These are the reason people say "LED don't work, ive seen it first hand"

Stick to fixtures with 3W CREE XP-G, XP-E or XM-L LEDs that have been proven.

My 2 cents

FYI I sell and work with LEDs on a daily basis so I know a few things about them.

Thanks man, I will wait to see your review in the next couple months before I make my decision.

Thanks
