I can give a 2 thumbs up for that Convoy T4. I just received mine yesterday, and was planning on making a post after I take some beam shot comparisons with other lights. I got the titanium with the Nichia 519a - 4500K. I'm using Li-ion 14500 cells, and it is great. It's rated for 800 lumens with the 14500s. I don't have a way to measure, but it's definitely bright, and the tint is perfect.
I have mostly cool tint lights, and a few of the warmer / neutral ones that I have are a bit yellowish. This is right in between, what I would call a true neutral. Looks great outside. I guess I'd describe it as what others call rosey. Lights up the church across the street that is 100 yards away. The titanium model is a bit pricey, but the standard version I would say is a great bang for the buck flashlight. I like it so much that I'm going to order a T3 titanium also.
I'd definitely suggest the 14500 cells for a light of this type, for brightness and runtime, especially if you're going to run it on the higher levels.
The programming options are very versatile, but, on the webpages where is says click 10 times to go into programming mode - it is actually 20 times.
Here's the one I got, but it's not where I ordered it from. It shows a wider variety of emitter color options than the link above.
