haha.. had a good laugh at the brochure myself.. That brochure was way more entertaining the the stuff that comes with premium lights.. :D I have a picture of mine in my overview that I posted earlier today..
Your Tangsfire and my Lustefire are basically the same lights it seems. But mine had larger wires and a faultless lens.
If you got 3 amps at the tail with 3 batteries you got even higher numbers than me. I was seeing 2,6A at the tail/ up towards 7,8A dived on the emitters. Not sure why that is only a 3 star rating in your book.. WAAAY beyond 18 watt! Far below 4300 lumen that Tangsfire rate it at though, which is no surprise with only 3 1st generation XM-Ls.
Lustefire says 2600 lumen, which is much closer I would say..
The driver in this light might actually be better than the 9 amp driver you mentioned... Based on the mod Relic38 did, its probably the best driver for 3x MT-G2s out there.. (assuming its the same)
As always, looking forward to see your mod on this.. Mine will probably take a long time before its 100% properly done.... Ill be aiming for throw.. :)
Thanks for the review! :)
