I recently purchased a great LED
light on Ebay. I wasn't sure if it was going to be a good buy or not as the price wasn't too bad.... and seemed that to get a GOOD LED
aquarium light you usually have to spend $80+ or more just for something suitable for a 20gallon.
I have browsed this forum for awhile but never posted but had to register just to recommend this light when I saw your post. I hope it's OK. I'm just going to give the item number as I haven't read the FAQ's yet to see if links are OK or not. The item number is 110854656115
I am not that guy nor do I know him at all. I'm just really excited about the light and will be buying more. It was a LOT brighter than I had anticipated. I haven't had it long enough to know how it will do for live plants. I have it on a 30 gallon tall right now and the light penetrates better than expected to the bottom. I had originally bought it for a 20 gallon but needed a temp. light on this 30 gal
. tall for the time being.
It has like 4-5 blue LED
's for a night light function. It looks beautiful with it on, but I don't use it every night. The shipper is in the US and I got the light 3 days after paying.
I haven't seen the Marineland light you mentioned for $40, but I doubt it would be as big or bright as the one on Ebay.
