Amazon has the SuperNight 12x Cree for only $59.99 and free shipping. I didn’t use my Prime account and still got it in 2 days to New York. Had the same high power driver used in the Lightcastle version.
I like the first one, but it's a lot of money to put into a light without knowing it performs well or having a driver that supports 5 batteries if the original driver performs poorly.
I really wanted that 18x cree version with the side switch, but the thought of having to purchase 5 cells killed it for me. If it was properly driven, and could be used in a 2 cell or even 3 cell configuration, I would have made it part of my collection. I also believe, but not positive, the XM-L’s used are upwards of about 8500K, so it may shine with a fairly cold tint, or very blue in color.
Just make sure you only use it with Un-protected cells of very high quality. If your batteries are good, it’ll illuminate on High mode, if not, it’ll flash then bypass high mode and go to strobe. I have a set of KeepPower 5200mAh Unprotected 26650’s arriving today. I’ll let you know how they work after a quick top-off charge.
The 12 emitter lights seem to be the way to go. The 15T6 I got (different brand, maybe Ultrafire) had 4S cell holder (Could run on 2 cells too), emitters were wired 5S3P, and had a very whimpy boost driver.
EDIT: Opps, posted the above in here accidentally.
No way to run an 18x off 5s cells with a FET driver. You’d need an extension for 6s cells and wire it 3p6s. Driver options are gonna be very hard to come by for that setup.
