I finally got the three HD2010 lights from Tmart today. I made a video review of them. Look at it and then let's discuss the options.

My vote would be to just buy the cheapest one and plan on a mod. If no mod is desired, then it's a crap shoot, with some people getting good ones and some getting not so good, since they are all made at the same place.

EDIT:

Remember I said in the video, that the spring might be the low draw on the Tfire light?

Well, I did a very simple mod on it and then I did it on the other two. I just soldered the spring back on and added Copper desolder braid to them. Here's a couple photos.

Just a piece of braid soldered top and bottom.

Here's the results:

Tangsfire was 3.25 amps, now it's 4.95 amps

Fandyfire was 4.25 amps, now it's 5.35 amps

No Name was 3.93 amps, now it's 5.05 amps

Remember, I am reading off the back of the battery, to the body, so you would also have to do the copper braid mod to the tail cap spring as well, to get close to those amps, but hell, why even mod the light. Just braid the stock light and run it till the led fries and then mod it.
