Product Information

Accepts optional pressure-activated DG and XT remote switches for precision control without altering grip on weapon

No, matter which one you go with you're getting a top tier light and it's going to perform like advertised.

Constructed from rugged aerospace aluminum, the X300 Ultra is Mil-Spec hard anodized to resist scratches and corrosion. It is also sealed to ensure weatherproof performance and is IPX7 waterproof for up to 1 meter for 30 minutes.

We know that it can get confusing when discussing Lumens and Candela, and we’ll leave that breakdown for another discussion. What’s important here is just how amazingly bright this pistol flashlight really is. After looking more closely at the data here, I’m thinking there isn’t much to see. All the lights are on the cool end of the spectrum, and except for the U-Boat, none of them even has a CRI over 70. Here you can see slight variations in output, flood, and color temperature. The X300U appears most dim. The other 3 lights are very competitive. Data Comparison Summary Measured Data The powerful SureFire X300 Ultra WeaponLight is virtually indestructible. Designed for handguns, yet effective for use on long guns, this light mounts securely to any MIL-STD 1913 rail.There is also a DC grip switch available for handguns that many shooters may prefer. However, we feel most pistol owners will prefer the standard switch. Another feature not to be forgotten is the versatile mounting options… First of all, let’s go over some of the specs of this light. This light is bright with 1,000 lumens of total light output. It has a moderately tight spot with a measurement of more than 11k candelas and a beam distance greater than 200 meters. The Surefire X300U has a moderately tight center spot with ample spill. This allows you to light up a room while still giving you some reach to illuminate a longhallway.

That’s a lot of power, so you might ask how long you can leave the Surefire on. Runtime to 10% of the initial output level is given as 1.25 hours. The PLHv2 performs under the Ultra but better than the Turbo and OKW until about 5 minutes in, where output matches the X300T then drops under the Turbo after about 15 minutes. My point in this I guess is that you should read the user manual before you jump to conclusions, right?
