spider72: I bought some of those 1W Leds. Some of the lenses are scuffed (that's probably why they are so cheap). They don't seem to be damaged too much. They look like they've been lying around the floor or something. Just so you know, they aren't in perfect condition.spider72 said:Nice work again SuperColey1
I am going to build LED light for my small 35 liters Arcadia tank, and I am going to use 14 x 1W lumileds instead of 3W ones, because tank is quite small, 1W leds have better lumen/Watt ratio and as I learned from Apsys post, they are not emiting too much heat.
If somebody is looking for 1W lumileds, here is where I have found quite chip source: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0302227030 these have batwing radiation pattern.
If you can afford it, I'd get one of these. It drives up to 9 x 1Watt LEDs, and you don't need to worry about the voltages or transformers or anything like that. It senses the number of LEDs you are driving.BINKSY1973 said:Anyone know of anything else avaliable? im looking to drive 8 to 10 1w leds.
Thanks for the tip. Did you put some solder onto the wire first? or are you saying there is solder on the plate of the led?SuperColey1 said:what I did was hold the wire to the solder plate and then press down with the soldering iron.
