Well yesterday Cabela's was having a huge sale and my girlfriend's father has been wanting a gun case for his revolver, so I went up there to see what I could get. Naturally, I stopped in to the flashlight section to look at the SureFires. I also looked at the Cabela's brand lights, many of which are exact clones of SureFires.
They had XPG turboheads as well, which were on sale. I ended up getting a 9V turbohead for $15 and putting it on my G2 with 2 AW RCR123As and I am impressed with the result. It puts a huge spot of light pretty far out there. I don't have any other turbohead lights, but I was definitely wowed. I expected a lot of throw, but it also has plenty of bright spill. The tint of the beam is very white as well. Very nice. I've seen one thread on here in the past about these, but I wanted to let you guys know that they may be on sale at your local store and they are worth checking out.
Also, I have one question for mdocod or anyone who can answer. Would I see an increase in brightness on this head if I switched to IMR cells? I am wanting to build a 2xIMR1634 light in the 200+ lumen range but I am still unsure about the properties of the cells. I have perused the compatibility chart, but I feel like understanding of the basic principles behind batteries and lamps eludes me, so I don't want to ruin anything. Any answers are appreciated.
