Light Education: How to Read an Output Graph
In my last Light Education post, we talked about how to read a spec sheet. The spec sheet tells you where a light starts. An output graph tells you the rest of the story. At Low Light Defense, we publish output graphs for the lights we test. They can look intimidating at first, but once […]
The Glock GTL II is back!
Glock released the GTL II back at Shot in early 2025. However, it quickly was out of stock for pretty much the rest of the year. Then earlier this year (2026), it seems Glock restarted shipping the product. Per our review on LowLightDefense.com, it’s light that looks like it belongs on a Glock pistol, following […]
Light Education: How to Read a Spec Sheet
In my last Light Education post, we talked about the difference between lumens and candela. But knowing what the numbers mean is only half the battle. You also need to know how those numbers are measured, because a spec sheet can be technically accurate and still mislead you. One thing I’ve learned over the years […]
Olight Launches the PL X GL: Laser + 2 Beam Profiles
Earlier this year, Olight launched the PL X pistol light. This light has a slick form factor, good switches, USB-c charging, and a design that looks good on the pistol, especially Glocks. I reviewed the light here. Though this is a new light, Werkz has designed holsters for a ton of different pistols when fitted […]

Surefire Adds Power to XC3 and XC3 Sub
Surefire has increased the specs on their XC3 and XC3 Sub lights. Both of the lights now boast the following specs: Lumens: 1,000 Candela: 13,000 These are respectable outputs for these small lights. By comparison, this matches the TLR-7 HL-X Sub specs (when using a SL-B9 battery), but lags behind the TLR-7 HL-X (–not– Sub) […]
Light Education: Lumen and Candela
Lumens vs. Candela: What They Mean for Your Pistol Light If you’ve shopped for a weapon-mounted light, you’ve seen two numbers advertised: lumens and candela. They measure different things, and understanding the difference matters for a defensive pistol light. Lumens: Total Light Output Lumens measure the total quantity of visible light a source emits in […]

Werkz has right hand versions of the M6 IWB holster […]
Werkz Expands Modlite PL350 Holster Support
The Modlite PL350 has received a refresh this year, with the option of fitting the blazing OKWv2 head on it. This makes the light one of the most powerful on the market. Werkz introduced Bisect light-bearing support with the PL350 a few weeks ago, and now is happy to announce expanded support of the light […]
Holsters for Coast PTX30R, PTX35R, PTX65R
We saw the Coast pistol lights at Shot Show this year, and were immediately intrigued. It seems all light manufacturers have been struggling with satisfying the needs of customers who want more “flood” style lights, while meeting the needs of those who want all the candela they can get. Coast thinks they’ve solved this problem […]
