50W White LED 1700 Lumens/Flat Lamp Light (18V~20V/2.5A)

What would this monstrous thing could this be used for Traffic lights? I cant imagine it giving any kind of focused light probably anything in the 160*. for $98 bucks geez in DIY parts and tools there is two other ones less lumens

That thing's just 50 1W dies soldered together.

nevermind

Commercial or home lighting perhaps?
I like it!

I dont know what I would use it for, it is really cool.

somebody hurry up and put it in a mag host! And then put an aspherical lens on it so we can put HID's to shame!

Man, if I could figure out a way to shoe horn that into my ARC AAA..... then put in a small nuclear reactor.....yeah baby!

Haha thats funny a nuclear reactor! But really anyone know what this could be used for just curious.

Hmm...

Claims 34 Lumens/Watt for $98. Somebody obviously thought it was worth manufacturing this thing. That's the problem with manufacturing in an environment which is changing so rapidly, things get obsoleted quickly.

You could use this in any kind of flood application, or indirect. Easy to apply, 50W in a single module, and good efficiency is easy to achieve in a linear constant current regulator. It is quite a lot of light from a small area, so a soft beam is probably achievable with a suitable luminaire.

@ 18V and 2.5A, these are arranged in series/parallel so I have some questions about current hogging. I guess they've thought about this tho'.

It's a bit too expensive, I think. And not quite efficient enough. Lots of LEDs at this value point are still selling however.

I'd have LED lights throughout the house, if there were real, economical and attractive looking solutions out there, but the really good stuff hasn't even started to be designed yet.

That's more power than most CPU. You'll need to glue it to a fan cooled CPU heatsink with Arctic Silver epoxy.
