Actually, I ran one of those on my XCR up until about 2 years ago. During the low-light portion of a course, I figured out that it didn't have enough umph in the way of range.
Something more 'directionalized' is called for IMO.
After that, I started trying lights just to see what I could find that would work. What I wound up with was a Tiablo A8 special edition with the 'one stage tactical forward clickie' (I had to learn to speak flashlight to get what I wanted - that means "like a Surefire" HA!).
These things pump out about 250 lumens, with great throw. Let's just say that anything I need to shoot at is lit up. They're STINGY on batteries too.
You can pick up the A9 now, the A8SE is long gone. The A8 was optimized for use with 18650 batteries - which I do use. They last just over 4 hours (!!!).
I got mine from Batteryjunction.com, but they're out of the lights themselves. They've still got the clickies though.... that and an A9 from ebay (note, I haven't bought anything from the hongkong sellers, and can't recommend them for that reason) would be well within your spending limit.
I run a surefire G2 LEDwith a Z49 tailcap. I haven't found a limit to its performance yet within reasonable distances. We did have to clear a warehouse and some of the deep corners were over 100 yards and it couldn't quite reach that far. For a start, I think it is a good, reasonably affordable choice. I have played with the G3 and it wasn't worth the extra weight as I couldn't see an improvement in performance versus the LED G2.
I am looking at a 250+ Lumen drop in bulb from tacticalnightvision.com for $44.99. It should light up those long deep corners.
For all the home defense scenarios I can think of, this is plenty. If I was concerned with being in large outdoor spaces or clearing massive warehouses, I'd get a larger flashlight. However, an important consideration is if you're in your house in a smaller room or hallway and your night vision is adapted to the dark, firing up a flashlight that is too strong during a sweep can blind you almost as badly as the goblin on the other end of the beam...
To quantify that concern, lights over approximately 80 lumens can have that unwanted effect.
Botach hosed me on a uni-max laser. Sent me an e-mail saying it shipped and then a week later when no laser showed on my door step, I had to call them several times just to get someone to answer the phone. After about 30 minutes on hold, I was told it was back ordered and would be at least two weeks. Of course they had already charged my card. I quickly canceled....2 1/2 weeks later, about the time I was going to call my CC company and contest the charges, I got credited back. Botach is a horseshit operation and I will never do business with them again.
For those looking for a really bright light with a lot of throw, here's an idea. Go to eBay and find a Surefire 6p incandescent. I picked up 3 for $35.00 each recently, but they can almost always be found for less than $50.00. I then installed a Malkoff Devices drop in LED unit for $50. The Malkoff Devices LED is rated at 240 lumens for 90 minutes. I had a Daniel Defense offset flashlight mount which completes the package. Total cost $130.00.
I went with the Tiablo A9. It seems to be a lot of light for the money. Got 2 of them off ebay (seller: kit-tronics) for 65.00 each on the "make offer", with free shipping. Who knows, maybe he would sell them for less. I almost went for the Deal Extreme deal but they were out of stock and I've heard some bad storys about them. I'm a little concerned about my mounting options with the wider head on these so if anybody has any ideas or experience mounting these I'd love to hear about it.
