I'm going to go with Streamlight and Pelican.
Both offer lots of bang for the buck.
The Streamlight Luxeon 3AA that I have has a very good bright white beam (with slight rings and blotches that keep it from being an excellent beam), and feels well made at a price of $35. Great house light.
My Pelican M6 LED has the best beam I've ever seen in a Luxeon
LED (pure white, no obvious imperfections), and can be bought for only $60. Great house light, great carry light, simply a great all-round light.
But with that said, if I could chose three companies Arc would be #3. They work very well, but I'm usually not a fan of super small flashlights--they don't feel as good in my hand as a light with more to grab onto. As an EDC light, its hard to beat Arc though.
Elektrolumens gets an honorable mention for producing high quality lights at good prices that use easy to find batteries. My 1 watt blaster does have a greenish tinted beam though. My three watt Hyper-blaster has a whiter beam, but no where near the level of beam quality as the Pelican M6 LED.
