I've been happy with DC input LED drivers from ledsupply.com. They also have AC input supplies, but I haven't used them.
For cheaper stuff, you can peruse Deal Extreme, but their site is rather a pain to search. -- Ralph ________________________________________ From: Gregg Eshelman [[email protected]] Sent: Monday, March 28, 2016 4:57 PM To: Enhanced Machine Controller (EMC) Subject: [Emc-users] OT: LED driver No reply on the candlepower forum, but nearly 100 views of the post I made. Since that forum is all about LED lighting, I expected someone to have a suggestion. I have a couple of LED motion detector lights, each with two Bridgelux BXRA-56C1000-A LED modules. Nominally rated at 1000 lumens each.The motion switch is a self contained 110 VAC switch, so all I need are replacement power supply/drivers with 110 VAC input which will fit within the lamp bases. The original supplies went *poof* but the LEDs are still good. They are in large die cast housings that provide ample heat sinking, but without any compound between the aluminum LED star plates and the bare metal mounting surface, so I'm putting some compound on. Available volume in the base is about 4.25" diameter by 1.25" depth. >From the LED datasheet mA Volts Watts Lumens115 25.3 2.9 395250 26.5 6.6 850350 27.3 9.6 1150500 28.4 14.2 1580 The output connection on the dead supplies in the lamps are marked 800 ma 35 volts. At that power, the lamps will put out enough light to brighten a wall 20 feet away on an overcast day. I don't think I need quite that much light in front of my shop or on my back porch. ------------------------------------------------------------------------------ Transform Data into Opportunity.
