Question: Is the clear lens made of plastic or glass?
Document: Plus it slightly cheapens the overall look of the light.- Make head/reflector assembly easier to disassemble, so that the plastic lens can be more easily replaced with a custom glass lens.The Mag-Tac is highly recommended. A solid, quality lighting tool that is satisfying to own and use. Order it with a Nite-Ize holster for a great combination.
Not much difference between the plain and scalloped head.The plain is ten lumens less 310 .It also has a low setting where the scalloped does not, that has a strobe.Same as the other I do not like the plastic clip and key.Same three volt batteries CR123 Seem to last long.USA made and it's a mag lite.I am a  mag fan. I would recommend this one also ,but pricey as well.
But even at this elevated "low" setting, the light provides excellent run time.Wish list for an upcoming "non-tactical" model based on this body and electronics:- Make the user interface programmable, and add a second level of "low" (around 10-20 lumens). Programmability such that the user can select the order of high-low-momentary actuation.- Provide a holster, rather than the plastic clip.
Received my light yesterday. Arrived very quickly and was in a cardboard wrap around the sealed plastic display container. It came with two CR123A batteries, a clip, and a tool for modifying the clip. I unscrewed the back, slipped in the two batteries, slid the clip over the Harrell, and screwed the back onto the barrel. I pressed the momentary switch for full light capability. I depressed and the light went off. I clicked the switch twice and the brightest setting stayed on.
Bought two,one for my Work bench and one for my car.Seems to be well made for the dough it costs.
Anything made by Mag-lite has to be good. At 210 lumen it is plenty bright enough and the beam is forcusable.
This flashlight is amazingly bright for its size. It seems very well made, rugged, and is light to carry. The tail-switch is practical.
Excellent flashlight! Extremely bright with 310 lumens to back it up. Made in the United States of America. Enough said.
I loved it so much I bought two more! One for my dad and one for my uncle. They made great Father's Day gifts!
Very nicely made and has a very bright light. I bought this for my wife to carry in her purse. It remains to be seen whether the batteries are readily available, when needed.
Answer: yes
