It vibrates/hums on all settings.
It is bright though! May want a little more out of it (am I too greedy?? I feel the POWER!!!)
Thank you,
Paul
Too greedy? You’ll find out once you mod it.
Hint: the humming is trying to tell you something. 
I don’t want to burn it out, is that a possibility??
Um, yeah. It’s possible. 
Only one way to find out for sure though.
These 12x lights when pushing any power cannot be run for very long. Your light is right around the limit I’d say. if you only want a massive output for a couple of minutes, then you might get away with an increase. I do not have one of these, but there are threads on here about modding them. Most involve installing a new driver from Kaidomain.
Good luck with the mods. If you want to try something with your existing driver, post a few pics of it and we’ll help you blow it up increase the output a bit.
Hi,
Thinking about splashing out on a huge 12 LED Skyray, well take a look here at the junk being passed off on eBAY
http://www.999wed.com/skyray_torches.htm
Assuming of course you can find a genuine seller to sell you either a fake or one that puffs out lovely blue smoke.
When you finally get your torch don’t be surprised when eBay supports the seller and leaves you the victim of fake or shoddy goods.
Cheers.
Aidie.
