The deep dish parabolic reflector throws a tight beam with strong peripheral illumination.

The light's case is made from a lightweight nylon polymer and comes with a comfortable rubber handle that provides a secure grip even while wearing gloves. Its LED is protected by a thick polycarbonate lens that is virtually unbreakable. The SL-20LP is O-ring sealed to prevent any ingression of dust or water. The durable light has earned an IPX-4 water resistance rating and an impact resistance of 1 meter.

Excellent light
January 9, 2019
This Streamlight SL-20LP is an excellent light. Even though it is a full sized professional grade flashlight, it is lightweight and very comfortable to hold. The beam is able to clearly light up objects far away. It also accommodates a traffic wand and is very bright for directing traffic, if needed. It easily slides into its charging sleeve (charging sleeve and power cord(s) included with the AC, DC or AC/DC models, not with the base model) to give a very convenient way to charge the flashlight. With 2 hours of run time at the brightest setting, it is very easy to switch to the low setting to get what is advertised to be 50 hours of use. I find the low setting to be more than enough brightness for many uses. I feel this light is more comfortable to hold than smaller flashlights and the beam of this SL-20LP light is much more powerful (it is rated at 60,000cd) than smaller lights that are advertised with more lumens. Last night I used the flashlight in my back yard and was very impressed with the brightness when shining the light at some distant trees. This SL-20LP is very useful and is a light I will be using for many, many years to come.
