Streamlight TLR 1 HL - Best Overall

The Streamlight TLR 1 HL is the best Daniel Defense H9 light that doesn't break the bank. This light has an incredible 1000 lumens output for lighting up a scene, allowing you to clearly see what's ahead.

The wide beam coverage provides a broad view of your surroundings in low light to identify persons of interest or potential threats.

The TLR 1 is designed with ease of use in mind, featuring a toggle switch that's incredibly user-friendly. You can activate the light or its strobe function with hardly any effort, which is a huge advantage in high-stress situations.

The ability to operate the light smoothly with just one hand is much easier than the Surefire X300.

Surefire X300U - 2nd Best Duty Light

Choosing the Surefire X300U for your Daniel Defense H9 pistol is a great choice. With a balanced throw and spill, it offers broad lighting similar to the TLR 1 HL.

The X300U's extended bezel that goes beyond the muzzle is a smart design choice, particularly for ensuring the slide stays in battery during close-contact shooting scenarios.

Durability is another strong point of the X300U. Built to military specifications, it's made to withstand repeated recoil and should height drop impact.

The Streamlight TLR 7A Flex is an excellent choice for those who use the Daniel Defense H9, particularly for its compatibility with subcompact firearms. 

This light shines in a range of situations, from night-time shooting to search operations and personal defense, casting a bright beam that reaches out to 40 yards. It's the kind of tool that adds confidence in low-light conditions.

What really stands out about the TLR 7A Flex is how light it is. Weighing in at only 2.4 ounces, it's so lightweight that you hardly know it's attached, which is fantastic for concealed carry.

The slim design deserves a mention too. The light's bezel doesn't stick out past the muzzle. This makes drawing and holstering smoother and faster, which can make all the difference when every second counts.

Olight PL Pro - Best Battery Life

One of its standout features of the Olight PL Pro is the USB charging capability. This makes the light not just convenient but also cost-effective, as you can easily recharge it without the need for constantly buying new batteries.

The PL Pro provides powerful illumination that's on par with other top-recommended lights for search and personal defense

I've had great experiences with the Quick Detach (QD) Lever Mount, especially when it comes to mounting it on a Daniel Defense H9 M1913 rail. The fit is snug and secure, making it a reliable choice for anyone who needs to switch their setup between different firearms quickly. The new PL 3 actually features a recessed mounting screw that won't snatch on things.

Another standout feature is the positive control switch. It's designed to give you a solid, tactile response, which is incredibly important when you're in the thick of things. Even with gloves on, you can feel that click, ensuring your gear is activated exactly when you need it.
