Ok, I bought both these headlamps through Amazon so, service and delivery were equally satisfactory.
I wanted to buy one of each so my kids would have one and I would have one when we're out hunting. ...so far, they've been used to search the cellar for hunting gear and locate frogs. From the little bit that _I_ have been able to use them, I'll post my thoughts and you will have to make the decision on what qualities are most important to you. For, they are both great headlamps.
To establish what I'm comparing:
Princeton Tec Remix - single Maxbright LED (white) and 3 Ultrabright LEDs (green) - rated at Power: 70 Lumens
Streamlight 61081 Trident HP Headlamp with 1-White and 3-Green LEDS - LED rating: 2000 candela peak beam intensity; 50-Lumen
Brightness: Ok, this is probably the most cut and dry topic. I'm not up on the technical talk of comparing lumes or whatever..I just wanted to know how bright these were. Streamlight is, by far, the winner in this category. Even on its low subdued (green) setting, it was brighter than the Remix on High. If lower power is necessary for you, this would be a negative against the Trident. For me, I wanted some power. For perspective, I could spotlight (white) a tree 150yds out with the Trident whereas the Remix died out between 60-75yds. Perhaps that's what the "peak beam" means....anyhow, Streamlight is much brighter.
Size: Remix 2.92 ounces vs. Trident 8 ounces. Ok, so this is the most cut and dry. However, I won't say that the Trident felt heavy or awkward. If you're running, you'll probably want the Remix. Walking to a treestand or bloodtrailing....who really cares? It wasn't a factor for me.
Comfort: Again, here I was surprisingly pleased with the Trident. The Remix is the most comfortable, but at less than half the weight, it's a given. The Trident has a nice padded backing on it to make it very comfortable for its size. I haven't tried the alternate strap that comes with it (similar to the one the Remix comes with). You'll have a reverse Mohawk, but if I've been hunting, I don't care what people think afterwards. To prevent talking exclusively about the Trident, I'll say that the Remix is one that you could forget about having on your head....it's that comfortable.
Stealth: I know it sounds like I'm handing everything to Streamlight on this review, but this may be the game changer. When adjusting the light head, the Trident has the WORST clicking noise I've ever heard on a headlamp. Yes, it will adjust the beam, but unless you're already busted or noise discipline is not an issue, adjust this to the position you'll want it and LEAVE IT ALONE!!! I'm yet to find any way to quietly adjust the head. The Remix...short and sweet, it's silent and prety solid in the adjustments. That's to say that when you silently adjust, it locks into positions so you won't be bouncing around.
Ease of use: The Remix has a hold process where you turn on and hold the button to activate the high beam. Probably pretty simple, but if it's already on (low) and you want to go to high, you have to turn Off, then on (and hold) to get high beam. Mildly inconvenient but efficient. Trident is straightforward. Low subdued, High subdued, crazy bright white. You have to cycle through, but how hard is it to cover the light with your hand to turn it off?
Misc: On a final parting note, be mindful of where you store these headlamps in your hunting pack. It may be obvious already, but these are easy to accidentally turn on. The Remix is proably less prone to this than the Trident, but it's just something you want to watch out for.
Hope this helps in making a decision. I'll just say that I'm very pleased with both lights and glad that I have them both for the purposes they'll serve. These are both very high quality lights.
