When using as light how bright does these get?When using as a strobe how bright are they? How quickly do they recharge?

Full power strobe they put out enough power to set my camera to f/16, ISO 100, 1/250...they recharge less than 1/2 sec...they have model lights but I don't use them so I don't have the measurements.

Hey Tim,They basically work as strobes only and not continous lights. At full blast, they get really bright. Also in less than 5seconds they can blast off again. Even though i don't take them to the extreme so i don't burn them

Not really. They do give decent light right away, but they get to full brightness over about a minute. Where I use them, it's not a problem, but if it was over my desk it might bother me. (Interesting that I now see two people said yes. We all must have different ideas of "instant on" means.)

If you want to use it as a strobe, it isn't, but with little CFLs like these you'd hardly notice. It's those big, like 200-400 watt equivalent CFLS that take a while to warm up the stuff inside.

They seem just fine to me. They are not powerful batteries. I've only seen them in things that don't need powerful batteries. Mine are for use in a small flashlight and seem to hold power well. No dimming in the 6 weeks that I've been using this set.

They are bright enough. However, I've been having problems with visible pulsating when the lights are dimmed below 60%. Not totally noticeable with the naked eye, but the pulsating appears on the video in post production.

They work very well in bright light or overcast outdoor lighting. They light up like they are battery operated as long as they have some sort of light to illuminate the fiber optic tube. In the dark they work just like any tritium night sight. During the low light times where there is not any overhead ambient, or artificial light and it isn't yet dark enough for the tritium to help out, they are as hard to see as any other sight. No single handgun sight is going to be perfect for all lighting situations, but these are as close as your going to get with current technology. I have these sights on all four of my Glocks and I really like them. They work very well in bright light or overcast outdoor lighting.

I have purchased four of these and depending on ambient temperature (the colder the shorter the life) the should last as one of the other posts states 9 hours on low, 1.5 on high and almost 3 on strobe. One of mine actually came with a battery that had a contact point(little button) that had come unglued. I am in the process of sending it back to get another. What I like is that they charge so quickly so unless you need more than the stated time you really dont need the extra battery, just pop on the charger for a hour and your good. The battery life indicator always lets you know if you need a charge so you dont get caught dead.

Not sure on high. On strobe about 2 hours. Battery could be better. Worth buying a bigger one

The strobe mode flashes about 3 times per second. It is not blinding and I would not rely on it as a personal safety device.

They don't light a room, but are bright at a proper distance. I use mine to read in bed. With the hook and magnet, they are great. They're cheap, and easy on batteries

275 Lumens, By far the best spotlight I have had so far. I use the 4 D cell batteries instead of the rechargeable. I've never had any luck with the rechargeable batteries. They never last very long. I use it to look around the yard at night when the dog starts barking. I've had it quite a while now and still have the first set of batteries in it that I put in when I got it.

They're faster than most; instant on and full brightness in about 10 seconds. I use them for many purposes.

no they are a rechargeable only battery. They are inbetween a AA and a C battery. This light is bright, but its not where near 3800 lumens. might be 600 or 800 lumens at the most. my streamlight stinger shines farther and has a more noticeable light beam. not to mention my streamlight lasts 6 hours on a extended life battery where as you get 30 minutes max with this flashlight

They only strobe. Either triple or single flash, variable speed. There is no steady on switch. I thought that was silly, but they still worked for my purposes. If you are good with electronics I'm sure you could do some re-wiring, but the wires are tiny and it's complicated.

I think they only flash when you're low on battery. These things are pretty small. I like them.

Depends on the situation you are using the for. Just darkness...then yes they are bright

I think they have an accessory flash, but try available light, you may like yhr trsults.
