Halo,
Just got this bulb from Ebay. It was new old stock, never used, and never open in it's original package. I opened the factory package and took the bulb out. Obviously it looked good and clear, but this is how it looks after 1 minute of use!
My MN15 is half or even less that darkened after 10 or 12 hours of use.
I powered it from two 18650 which works well with MN20 and it is not overdriven, unlike MN21 or MN16.
I'm afraid to use it more as it may blow and destroy my turbohead.
Any comments??
By the way I once had similar case of MN10 in M3, it behaved the same and after few more minutes got totally black and died, didn't blow fortunately though.
