I am a big believer in WML on all firearms designated for home/self protection - you can’t shoot what you can’t see.
I started this journey 20 years ago with a SureFire Nitrolon G2 in a barrel clamp mounted at 6:00 under my front sight assembly with “60 blinding lumens of incandescent white light” while attached to a regional SWAT team. That light was state of the art at the time and got a lot of use. Looking back, I don’t know how we got anything done with that little bit of light. As the tech improved, I went for the ride. First a Cree LES 160 lumen replacement head for the G2 - it ate batteries fast and got HOT! Then I went from the Nitrolon to a SureFire M500 handguard with integrated light at 200 lumens, then a SFM900 at 200 lumens with the built in vertical grip (that M900 was HEAVY!). Then 200 lumen SF Scouts, then a 500 lumen SFX300 at 12 o’clock on the pic handguard on my rifle. Then a couple of 600 lumen SF Scouts, a 1000 lumen 3 cell SF Fury handheld in a VTAC mount, then finally where I am now with the mix of Modlight PLHv2 and OKW models, and SF M600DF Scout lights on them with their 1000-2000 lumens and whatever crazy candela rating (which seems to be the new hotness when describing the potential effectiveness of white lights - even SureFire is pushing their candela numbers now). Each iteration was brighter and more effective than the previous.
I have also used lights from Streamlight, Cloud Defense, OLight, Inforce, and some others I can’t remember on my rifles looking for what works best for me. I found them all lacking in some way or another, and usually settles on SureFire as my go to brand, until 3-4 years ago when I tried the Modlight.
The lights we have available to us now are amazing. A literal embarrassment of riches - but they are pricey. IMO the Modlights (both PLHv2 and OKW version) are far and away the best, with the SFM600DF a close second - for my needs. I have not had a chance to play with the new CD REIN 3.0 or the newest iteration of the SF Scout, but I hear good things about both.
Define your needs first.
• What’s your use parameter?
- Indoor or outdoor?
- Range gun or defensive use?
- Average distance for shooting?
• How bright do you actually want it? (I’m a believer in “give me all of the lumens!”)
• Do you want throw or reach?
• Do you want a hotspot in the center or an even distribution?
• Do you want a clearly defined edge/aura or do you want it to “fade out” at the edge?
• Where do you want to mount it?
• What’s your intended “switchology” solution?
Then find the light that best suits them. Then get some training on how to use the light. It’s not as easy or intuitive as you may think.
If you choose from SureFire, Cloud, or Modlight you really can’t go wrong. Streamlight is a good budget option, and works great for a lot of folks. I have had nothing but bad luck with them and have quickly broken every Streamlight I have ever owned (except the TLR7As I have on my G19 and G48).
