Do you have a link?
Thanks for all the info guys. I still want to use 2 li-ions so how many lamps can take 8.4 volts without going
Of course I do
Here is the v3.1 reflector with a smo coating
Here it is with an op coating
They also have
this one also with a smo coating, but I don't understand what the difference is. OP-Version of this one
here.
They all have a bulb opening of 15mm. You need to make sure that the bulb you want use has a diameter of less than 15mm.
If I were you I would definitely take an OP-reflector to get a useable beam. I would take the v3.1 reflector. Seems to be newer. I own one of these and think it's ok. It does the job.
Prooftech over in the marketplace
also has reflectors. These have a smaller bulb opening of just 0,377" which equals 0.958mm. These are better for smaller bulbs like the ones from WA.
