"better in every way" isn't descriptive enough?
It's not really accurate either...
BrightStar Razor vs. Streamlight ProPolymer 4AA Luxeon comparison highlights:
- The Razor is made of nylon with a one piece head/body and screw-on tailcap. The ProPoly is made of polymer with a screw-on bezel retaining the LED/reflector module.
- The ProPoly has a forward clicky on the tail, and it's always felt a little awkward for me to use. The Razor has a reverse clicky on the side, just below the head.
- The ProPoly houses a Lux I, and the Razor a SSC P9.
- Both lights have smooth reflectors. The Razor's reflector appears to be roughly 25-33% wider and deeper.
- The Razor requires 3 AA's, and the ProPoly 4 AA's.
- Both lights can accept (and run on) Eneloops, but they're very snug in the Razor.
- The ProPoly is regulated, and according to the description at BrightGuy, the Razor is not.
- The Razor is slightly wider and longer than the ProPoly, but overall they are very similar in dimensions.
- Loaded with alkaline cells, the Razor weighs 5.9 oz and the ProPoly 7.8 oz.
- The Razor has a very intense hot spot, and very little spill. The ProPoly's has a much wider hot spot, and significantly more spill.
- To my eye, throw appears similar, but the amount of light pollution in my neighborhood is pretty high, so take that opinion with a grain of salt. Regardless, the hot spot from the ProPoly is 2-3 times wider than the Razor, so I find the ProPoly more useful as a thrower.
- The ProPoly has decent spill and the Razor does not.
- In a ceiling bounce test, the ProPoly appears to be significantly brighter than the Razor.
- I've read a few reports of ProPoly's shattering from high falls, and the Razor's switch is better protected from impacts, so if I were to speculate, I'd guess the Razor can probably withstand more abuse.
- The ProPoly is slightly more comfortable for me to carry, but the Razor's body has (for lack of a better description) a less smooth design and a slightly flared tail, so it's easier to hold on to.
I'd love to add runtime info for the Razor, but I don't have it, nor the equipment to measure it accurately.
Overall the Razor's not bad. I actually really like the nylon body and the position of the side switch. But it just doesn't put out much light, and what little light there is is concentrated into too small an area. If I didn't have either light, I'd spend the extra $7 and get the ProPoly.
PS... I was checking out the PT Amps at REI today. Very interesting! I wish they had open box models to try out.
