Alright, I had a chance to play with some of the new stuff.
My DBS already had an AR lens in it. The new lenses appear to be a little thinner. I didn't gain any output with the newer lens, so I kept the thicker old one.
My C2H's had non-coated lenses in them. Adding the AR lens did improve performance slightly. Probably a 5-10% gain.
I still need to compare the new DBS reflectors some more with the MC-E. I actually have the new DBS LIGHT OP XR-E reflector installed with the MC-E. This doesn't produce the best beam and there is a visible + in the hot spot, BUT it has more throw than the other reflectors (original DBS OP, and the new DBS OP for the MC-E). I compared the DBS with the new light OP reflector to the Jetbeam MX-1, Tiablo ACE, and Legion II, and it was keeping up with them very well. The Legion II edged it out, but the beams on the MX-1 and Legion II were no better and had slight donut holes, etc.
Also to make things clear, I was using the Dereelight 2.4A MC-E pill, which may not be available anymore. If I had been using the standard 2.1A I'm sure there would have been more of a difference between the DBS and the other MC-E throwers.
The other thing I got was the new 3SD Q4 5B pill! That's right, Q4! Dereelight now has these available. If they aren't listed on their website, try contacting Dereelight.
I have a bunch of Dereelight pills over the years and some of them had had slight issues with low PWM frequencies, inductor whine, etc. This new pill seems to have all of that sorted out. No noticeable PWM on low as far as I can tell, no noticeable whine, etc. I have the 3SD Q4 5B pill in one of my CL1H's with an OP reflector. I had a lot of fun using at yesterday's Photon Fest 12 hosted by Milkyspit. We all take a long walk to a nearby quarry and it was nice having the warmer tint.
So I still need to do some more comparing between the new DBS OP for MC-E and the original DBS OP reflector.
