I am considering purchasing an LED fixture, recently someone posted a link to a seller here, and I cannot seem to find it. Or I found the link but it did not lead to the advert I saw before. I wondered into an aquarium shop yesterday, and saw some interesting fixtures but they were going for up to $500 and more. Some they had used for $100, and cripes! Two plug ins, dimmable, two colors, seperately dimmable, timers, on and on it went. Evidently to pretty much mimic the sun. Which is great, but I think I need a lower end product, a cheaper one anyway. Surely some of those features are nice, but are they really useful? Separate controls, dimmers? The timer is a no brainer. Thoughts, ideas? I would like to find something in the 36 inch range, and with a way to hang that is adjustable, say ten to 15 inches...I forgot to mention three fans, I guess they all have/require fans? Thanks for any info.
