All you LED Gurus...

Any reason something like this couldn't be used for a landing light and/or strobe light?

Looks to be:
3.5 forward voltage
9 amps

35 watts
2250 lumens
$26

That looks like a very interesting module. The cree modules are over 1200 lumens and they are like looking at the sun!

I have been looking at these and the Cree cxa21011 which are even brighter. Trying to figure out what all would be needed to put two on each side on the duck works blank mounting plate.

Wow! That is a pile of lumens. But what matters is putting the light where it is needed, and that generally means a parabolic reflector.

This may be great for a Wig-Wag setup.

Mike,

I agree with you. The LED does have a lens and there are some data showing what look to be light patterns, but I don't know enough about this stuff to be able to fully interpret. Certainly they should be useful as strobes or wig-wag lights. I think the 9 amp current draw will be a challenge. I'd like to hear from the EEs on the forum.

3 issues
1) You have to control the current (controller or resistors)
2) You have to heat sink them so they do not get too hot.
3) You have to use a reflector to focus the light.

Also, good information here at a US supplier.

Probably the best way to go on the controller is at the bottom of this product page but it will not do the power your mentioned LED wants.

Take a look at this LED set up, all I can say is wow.

D,

Yeah, one of those would work... LOL
Problem is he's drawing 13 amps. He could hurt himself with that

Bill,

Thanks - reflectors are available, but I'm interested to see what the lens alone does. The unit looks to be 1 cm square which is pretty small. Maybe I can find ones that draw less current and use several. I may just have to buy one and fool around with it. I haven't found a 9 amp CC power supply yet, but they should be out there.
