All just my opinion.

I had a set of XGT's on my last patrol with the light blue lens covers, with spot and spread. Absolutely loved them. (Cost about $550 for a pair.)

Bought a BT50 with a set of IPF 900 extreme's, 1 spot, 1 spread, with light blue covers. (about $450 the pair, I think, only because the XGT's didn't fit.)

I think the XGT's smash the IPF's. left them for dead in real world light output. I don't know the figures, but they definitely appear a lot better.

I have also used a handheld lightforce 180 (i think), and found the 240 XGT's also left it for dead, there was 2 of them but.

I am wanting to upgrade my XGT's to HID for my new patrol in a couple of weeks, we'll see what SWMBO says, I guess.

I guess it all comes down to what you need versus how much you want to spend.

Good luck with your decision.
