10 lumens. how does one describe how bright something is? just enough to find your way around the woods at a distance of 10 meters. there is a red lens cap for sale on amazon that is specifically for this light, but if red light is what you want, then i would buy a light that has a red led instead of capping a non-red led. more efficient, more throw... if this is what you want though, you cant really beat the t20 for EDC purposes.

If you have the lens cover, or can find one. Its a very nice bright light. There is no lower power setting that I can find.

Depends on if it's an XM-L T6 like it says, or something else. The first one I got wasn't even the same class of Cree bulb, the second was an XM-L U2. From what I've seen online the U2 is around 5700k and the T6 is around 6500K. This also seems to match up between the U2 I got here and another light I have with an actual T6.Of course, the permanent button memory and lack of adjustable focus kill this flashlight for me. It's bright, but I don't recommend it.

Bleed isn't too bad, but I wasn't impressed with the light quality. Its a downward cone. I've since moved on to a d120 style light from reef radiance. Similar pricing and I'd you wanted even cheaper there's one up on eBay for like a hundred that not programmable.

There's 3 different beam. high medium low. Strobe and SOS. Too me I don't think u need it any brighter. We nicknamed it the sun

Would be good for this. It is maybe 15 inches high and maybe 8 inches across at the widest point. It is an LED light, so it is a soft light, rather and a powerful direct bulb. Although, would be cheaper and just as useful to buy a simple flashlight.

The coatings actually helps the light to pass and make the images brighter. But I feel magnification of 16 may not be powerful enough for astronomy purpose. And still, a tripod will be helpful to get stable images, unless you have very steady hands.

I would think it would be common sense to believe the website. LED Lensers are under rated. My M7R is as bright as a 600 lumen Streamlight.

The body of this flashlight is a 1" diameter...which was one of the big selling points for me. It will use a standard 1" picatinny scope ring. The lights were so inexpensive I bought one red and one green, and a pair of cheap throw-lever scope rings, so I can swap them out depending on what I wanted with them.

This flashlight has a 275 degree spread without the use of the zoomed in feature. It will illuminate my whole front yard out to 100 ft LIKE IT IS DAYLIGHT in TOTAL DARKNESS. YES.Zoomed in it is around 3 degrees +/- on axis...Meaning 3 degrees above and below 90 degree angle= 6 degrees TOTAL @ FULL ZOOM...It looks light a "Light Saber" from Star Wars and it good for spotlighting a bear at 100 ft (pretty much JUST the bear, mind you, everything else is UN-illuminated) and good for 200 ft at full zoom. Really COOL! Eats batteries. Get the 2x 3.7 volt Lithium-Ion w/charger. Use it like a sniper (short bursts) and carry a spare...You'll be happy!

"Useable yes, easy no" is my experience. If the sunlight is really bright, it is hard to see the red dot. Not a problem if you are doing simple distance measurements, but triangulation did not work well for me. It's great on a moonlit night!

I haven't dropped any of my Thrunite flashlights so I can't respond on the dropping issue. I have 3 of the Thrunites and the tn35 is by far the best and the brightest ! My tn30 mini is rated at 3200 lumens and my tn35 is brighter. According to reviews, the Thrunites are pretty accurate on their lumens ratings

Send it back while you can. The batteries are expensive, not good for much else, and my light fried after a couple of months. I bought a Weiita H807 Starlight LED Headlamp, 300 Lumen headlight found elsewhere on Amazon. It uses good old AA batteries, provides plenty of light, and has been going strong since the first week in Sept. My son also has one of these headlights and we use them on a daily basis.

I bought the light and it is plenty bright. I think the true output is 520.The spot is very tight ans so using it to walk the dog is iffy. I added a removable diffuser to the lense. Another poing is that to turn it on you turn a knob. (Not what you expect).

The manufacturer did not specify. Suggest you contact UCO/Industrial Revolution. I'd guess and say the low level setting is about 2/3 to 3/4 less than high setting. Manufacturer says high is 150 lumen but I think its more like 100-125 which is still very good for the price.

It comes with a 20w bulb installed and a 20w spare. See the technical specifications http://store.amscope.com/t490b.html For a brighter source I would suggest an LED model... this one is rather dull, but it is sufficient for dark field photomicroscopy

I returned mine. The light was not bright enough and the magnification didn't suit me as I was used to something stronger.
