Sold/Expired Maximum voltage ROP can handle?

[jaybiz32]

Just wondering what the Maximum voltage the ROP high output bulb can be ran without worries of instaflashing te bulb? An experiances. How about the WA 1185 bulb?

With the ROP bulb, some people here are running 7 Nimh cells to push the bulb a little harder. I think they rest the cells for a little bit hot off the charger. But be careful pushing the bulb to the limits. Dont point it at anyone.

I used to use the 7 nimh cells on the ROP Hi and it worked great as long as I only used the light for 3-5 minutes or so. Any longer and I have had a 100% rate of exploding bulbs !

I have used my 18650's hot off the charger with no problems yet. That is about 8.4V when they come off my ultrafire charger.

I watched my friend instaflash a ROP high bulb with 6 sub-C's in his 4D....so be careful.

Yep mine will flash with 6 sub c's too, after an hours rest. I usually wait until it's around 7.8V before I use the high bulb now. Both spring fixes done on mine.

The low seems to handle it ok though, haven't flashed that one yet.

my 5c with 6 sub c's flashes even when rested over night and after using a LO bulb to bring it down to 7.8v.

It had all the fixes and pro-golded. My next ROP plan to only do one fix at a time.

I think a few of the other members reported that the built in resistance with the host is what's keeping the bulb from blowing. The ones that did either a switch mod or found a way to reduce internal resistance somehow, were the ones that reported a bulb blowing.

I read about that too late or didn't pay much head to that valid piece of info.

If a stock mag still instantflashes HO bulb. I wonder about adding an amp limiting patch to increase resistance like a 20g or 22g wire in the tailcap spring instead of 12g frequently used to decrease resistance?
