Oops, think I fried my first LED

The one on the left is from a working Romisen RC-I3, which can handle the LIR123A 1000mAH 3.6V cell, and on the right is the now dead Romisen RC-G2 that I fried with a 14500 900mAh 3.7 cell.

Naturally, I just had to try the one on the right with something other than the 1.5V AA suggested battery. It lite up for just a second then went dark, then I could smell something was wrong.

Congratulations! You've released the magic smoke. :twothumbs

We've all done it. It sucks but you also learned something.
 
My guess is that you only fried the driver and the LED is fine. No worries, the stock driver is junk anyways. Replace it with DX #7880 or #7882 and mount a real LED on the heatsink! I just did that with my RC-G2 this evening.

I'll pick up a Q5 with the 7880 and see what I can do.

AH that's a crappy cree anyway! Only 2 bond wires.


there's nothing wrong with XR-Cs, they are just made for applications that doesn't nuke it with 1000ma. A smaller die size also facilitates easier collimation.

I just wish they are cheaper:shakehead

if your LED fries, you should see brown residue on top or between phosphor. your CREE looks good, whats below the LED [aka driver] probably gave up
 
Look on the bright side - think how many Chip Weevils you fried along with that LED. A whole colony of them.

Could it be that the chip weevils compromised that integrity of the LED, making it more prone to releasing the magic smoke? Do the chip weevils need this gas to survive, or can they live without it, in normal atmosphere? :thinking:

As long as they don't evolve into chip roaches, which are nearly impossible to eradicate (some may even be able to survive inside HID bulbs!), we should be fine...

The smoke can escape through the burrows.
 
The LED looks fine, as other have said, you probably just fried the driver.

It's also an XR-C, which I haven't see with anything but 2 bond wires.
