morelight I set one up today

Matsnork I have used, dissected and re-built the 10w straight up cold white version and have seen many people using them after googling the subject. Two 10w units lit up my 24" tank. Medium light I guesstimate.

They are a good idea if you can get them cheap and dont feel up to the task to building a led from the same led chips/drivers found dirt cheap. They come with water resistant (claimed waterproofish but quality varies) casing if you plan on mounting them inside a hood. The glass is very thick and will eat up a lot of the light. Removed and the housing becomes a bit pointless imho, thus my diy comment below.
They added lots of led shimmer and grew my plants, removed them because I started to get algea problems (low tech non-co2 tank)

If you´re handy I would recommend buying the items needed from ebay and build one that suits youre needs. Much cheaper, and you can customize with active cooling different lenses/reflectors.

Edit: Found some old comparison pics of mine, dymax vs 10w flood led:









Some different test builds I made cpu heatsink with original reflector vs random heatsink found in electronics shop with 2x10w:







In the end this 36w par38 bulb was the best buy. Cheaper than flood, better focus, less shimmer, more light, easier to mount, better looking and so on...

I am thinking about doing the same. I think a bent piece of conduit as both the light hanger, and the tubing for the cable would make the DIY look very "finished". Still thinking about this on my nano but my ugly DIY light is so perfect in terms of light balance for my tank.

acitydweller i can tell you with fair certainty with experience backing that i was able to grow a healthy amount of algae with a 10w Flood sitting on a versatop. I use the COOL white which is documented at 6000k. This is a low tech setup for my crayfish and the glass is often seen with cray babies feeding on the algae.

talontsiawd No insight, just want to see where this goes. Some actually look pretty attractive. I wouldn't mind trying one of these on my nano but would love someone else to figure it out for me first . That's why I love this board lol, everyone jumps on these things and will have par data before I would get around to doing it anyway.

Sethjohnson30 I just used but connectors for now now I plan on soldering it when I add a switch

james1542 Nice Job Seth! Looks like it will make an awesome rack light. Did you end up soldering that to wire it or, use some other means? The 10W doesn't look very big you could easily cram 3 of them over a 10g. The 30W I have looks to be about 3x larger . So far the plants are loving mine.

Sethjohnson30 They are sold in many different temperatures mine is 6000k
12-02-2012 06:32 AM
Vincent Tran How do you know if they are the right Kelvin temperature or not?
12-02-2012 05:18 AM
Sethjohnson30 Wow I posted on too many threads about this subject I wired it up and mounted it
11-30-2012 11:54 PM
james1542 Have you seen this thread about these lights: http://www.plantedtank.net/forums/sh...=195589&page=2

There is a link in there to a How to on wiring these up.

I have the 30W on my 20 gallon and it is sufficiently bright. Me-I always want more light, but it has all my plants growing fast, including Erio cinereum (that may be due to some DIY CO2 as well..

Sethjohnson30 Well for some reason I can't upload pics right now

It has 3 wires

Sethjohnson30 I got the light today of course it has no plug........

Can I just splice a plug on to it? Or do I need some sort of converter?
11-24-2012 03:29 AM
Sethjohnson30 Well I have a soldering iron but I'm horrible at soldering(go figure a certified TIG welder that cant solder) hopefully mine plugs into the wall. I'm putting mine in my wire shelf rack....I will probably just attach it to the top shelf with zip ties lol
