what's a good bright budget light?

I own a BTU Shocker and yes, the Shocker is quite heavy, and also front heavy after loaded with batteries, not very convenient to carry around for long time. But it does come with a long and nice landyard and that might help a bit. Other than the heavy characteristic of the BTU Shocker, it is very well built and light output is really amazing.

I do not own a SP03 yet but I plan to buy one soon. You can check out for review here . The LEDs are driven not as hard as the BTU Shockers but they are XM-L2 U2 (better efficiency), lighter weight, 4 cells in parallel, and better heat management. But I think it is also a little front heavy.

The TK75 is another good option too, but the best price is around $150, not sure if that match your budget.

Cheers.
