Holosun white light 42000-2100 Review

First Thoughts on the Holosun white light 42000-2100

The Holosun white light 42000-2100 enters a crowded market of pistol-mounted lights, promising both impressive output and rugged durability. Made by Holosun, a company already well-regarded for its optics, this light aims to deliver a serious punch in a compact package. Does it succeed, or is it just another face in the crowd?

My quest for the Holosun white light 42000-2100 began with a growing need for a reliable and bright pistol light for home defense. My previous light, a budget model, simply didn’t cut it in terms of brightness or build quality, and left me wanting a better option. I wanted something I could trust my life to.

Unboxing the Holosun white light 42000-2100 revealed a sleek, black anodized aluminum housing that felt solid and well-constructed. The light is compact, weighing in at only 5 ounces, making it feel like a manageable addition to my handgun. The machining appeared clean and precise, inspiring confidence in its durability.

I considered the Streamlight TLR-7A and the Surefire X300U, but ultimately chose the Holosun white light 42000-2100 due to its attractive price point and the claimed 42000 Candela output. The Holosun’s smaller size was also a plus, as I didn’t want something excessively bulky on my pistol. The price of $169.99 seemed reasonable for the features offered.

My first impression was positive; I was excited to mount it and see how it performed in real-world conditions. The compact size and solid construction immediately suggested a quality product, but the real test would be its performance under stress.

Real-World Testing: Putting Holosun white light 42000-2100 to the Test

First Use Experience

I initially tested the Holosun white light 42000-2100 at an indoor shooting range in a low-light environment. The immediate blast of light was impressive, easily illuminating the target at 25 yards. The beam pattern was concentrated enough for positive identification, but still had ample spill for peripheral awareness.

I also tested the light outdoors during a light rain shower. The IP68 Waterproof rating proved effective, as the light continued to function without any issues. However, the wet conditions did cause some slight glare off of reflective surfaces.

Mounting the light was simple, and I appreciated how easy it was to activate with either hand. After about 100 rounds, the light remained securely mounted, with no signs of loosening or shifting.

Extended Use & Reliability

After several months of weekly range trips and occasional use during nighttime property checks, the Holosun white light 42000-2100 has held up remarkably well. There are a few minor scratches on the anodized finish, but the light itself is in perfect working order. The battery life is as advertised, typically lasting through 4-5 range sessions before needing a recharge.

I haven’t experienced any malfunctions or flickering, even after repeated firing and handling. The light feels just as solid and reliable as it did on day one.

The Holosun white light 42000-2100 requires minimal maintenance; I simply wipe it down with a damp cloth after each use to remove any residue. Overall, it has definitely outperformed my previous budget light, proving to be a significant upgrade.
