Glad to hear that you are pleased with the TN32. But if you would still like to replace the Dereelight with a similar sized light, go to the Eagletac website and look at the S200C2. The XM-L2 U2 is rated at 1116 lumens with a lux of 36,300. The warmer tint of the XM-L2 T6 has a little less lumen output. It is very similar in size and uses 1 x 18650, or 2 x RCR123A
I have a similar interest of replacing my Dereelight, but want something that will comfortably fit in my coat pocket. I have not yet purchased this light for myself, but it is the next one on my list.
