The HL4 has a poly covered machined aluminum body. This large tactical light generates a remarkable 2,200 lumens at 30,000 candelas. The front and rear have semi-aggressive strike bezels that would make an effective weapon. The body is easy and comfortable to grip especially with the poly cover.
- Construction: The HL4 is machined from aircraft grade aluminum that has a poly cover and semi-aggressive striking bezels on both the head and tail. The threads are tight and smooth and sealed with an O-ring.
- Size: The HL4 is large (8.6″ long) and would work well on a service belt.
- Waterproof: The HL4 is rated at IPX7 waterproof.
- Features: Has high, strobe, and low modes. You can also change the light mode using the Ten-Tap programming feature.
- Batteries: This light can use either two rechargeable 18650 batteries or four CR123 lithium batteries. Three rails in side the body that allow it to use batteries of different diameters. Recharge the 18650 batteries using a separately available charger.
- Light Output: (high) 2,200 lumens at 30,000 candelas for 1.75 hours, (medium) 600 lumens at 8,300 candelas for 4 hours, (low) 60 lumens at 8,000 candelas for 43 hours.
Advantages
This is an ultra high-power flashlight that can use either 18650, rechargeable batteries or CR123 batteries. Things I like about the HL4:
- Built to use either rechargeable or disposable batteries. Some rechargeable lights cannot use alternate batteries. Consequently, if those lights lose power when you are in the field then you are stuck without a light. With the HL4 you can run on rechargeable batteries but use CR123s as a backup. I would never purchase a flashlight that could not use backup batteries.
- You DO need a separate charger and 18650 batteries for this flashlight. You cannot directly charge the batteries in the flashlight.
Disadvantages
The ProTac HL4 is an excellent ultra high-power flashlight. My only issues with the flashlight are
- Large size
- Rechargeable batteries and charger sold separately
- No case included
- For heavy use the rechargeable batteries would have to be manually replaced — you cannot simply plug in the flashlight to recharge the batteries
Recommendations
If you are looking for a high-power tactical light then this is a good choice. This would be a good choice for first responders with the caveat being that the rechargeable batteries must be swapped when drained.
