Question: Can you adjust the beam or is it fixed ?
Document: Huge range, very strong beam. Very happy with size and weight. Streamlight HL 3 is perfect for home safety and outdoor activities.
This light is great and very bright. I have used it indoors, camping and hiking and even used it (the first day I got it) helping rescue a hiker on a trail. It is bright and provides a great amount of light. Is everything I expected from Streamlight. They delivered another great product and that is why I keep buying from them. With the narrow beam, this light can go very far.
very bright and illuminates for a long distance. i never thought i would pay this much for a flashlight but it was worth the cost
one of the best, brightest, flash lights I have ever used
a very good light thanks  I placed  on a AR223
This thing is bright and has legs. AND WORTH EVERY PENNY I PAID!Pros:Does everything is says it will do in the marketing material and does it well. Well constructed and made from quality materials. Temporarily blinds anyone when you shine the light in their eyes, so it make a great non-lethal tool, in addition to it being a flashlight, when dealing with strangers, yahoos or idiots walking on the street, in the parks or out in nature.
This seller is losing sales by not describing this product properly. Most seeing this listing will think its one of the older Protac HL's, but this is the new 1100 LUMEN PROTAC HL3  light they just came out with. Light is amazing! Will make daylight for about 200 yards
This light is awesome. It is very bright and will serve me well when needed. I am a big Streamlight fan and have bought multiple products from them.
This flashlight is awesome!!! !It's not a light to keep constantly on however.If kept on,these will heat up.Streamlight makes great products and this one is no different.ONLY problem is attaining CR123 batteries for them.They're quality made.5 stars.
This flashlight is absolutely amazing. lights up the night and then some. My only complaint was that the first one they sent me was defective. But not a big deal .. The retailer shipped a new one out right after  I sent the defective one back. The only thing was I had to pay the shipping.
Answer: yes
