LED floodlights

Anyone had any experience with LED floodlights? I can't find anyone using for freshwater planted tanks yet.

they are $30 max for a 10W LED I found some as cheap as $15 with free shipping. They also come in 20W and 50W, which is rediculously huge and go 3500-4500LM, pretty HUGE though. These are sold in every color spectrum, why they are a big deal for saltwater tanks right now.

I used one before on a 20 long shrimp only tank. If you hang it, it might work if not, the focus is too narrow.

I was trying to find a pic of it or the thread where it was discussed before. It might have been archived already. I went back through my posts and it only goes back up to 2011.

Would 1800LM be too much for a high light 20 long?

I have researched this a bit. My understanding was that the 10 watts are okay for normal depth tanks. Deep tanks such as mine, a 125 would need the 20 watt ones. In my case I would need ten of them for a 6 foot tank so for that cost its not that great for me. When my cash flow allows I will be going with the aqua ray 2. Minimum cost for lights alone would be 270.00 I have not seen actual pictures of these led floodlights mounted only just heard of it being done.

Couldn't really comment on that, depending on how you mount it. If you have it set up where you can raise it depending on your need, then it might work.

Really interested in these floodlights as they cheap here in uk, can get A 10 watt for about £10 , i have built a wooden hanger above my tank which these lights could be screwed to pretty easy and the bracket lets you adjust to the angle accordingly , would these be any good for a 16" deep tank?

Where there's a will there's a way

Someone needs to get one of the lights, then measure the PAR vs distance and distance from the centerline under the light. Only then can anyone say what it will do on any given size tank. If anyone has this data please pass it along here.

1+

Also if these are not dimmable you could have issues with your height.

I'm about to get 16 10w and grow something even if they dont work for my tanks. I am so excited they have cheap ones in the US they are RGBW color and have a remote control for $21 shipped. I really wanna have some NON planted tanks with nice ambiance lighting.

900 LM for a 10 w the 100w are 8000LM I believe there are so many different kinds. Careful make sure they have the LM value listed when you buy off ebay alot of defects on there.
