Can these really be used as a light source in the dark? I mean can you see other things in its light?

I love these! They are not as bright as a flash light but you can use these to walk around your house if the power is out

Sure. They're a good source of light, only problem is using them to try to see things where color matters. Don't try tracing electric wires with them, if there's any color code. But, if your power goes out, GREAT to have. Safe for kids, unlike candles. You're not going to read with them, but to keep you from walking into stuff, great.

The ambient light emitted can be used for tasks like reading but it doesn't project very dar--pretty much like any other mil-spec chem light.

Looks like its designed to imitate infrared emitters. These are used to enhance nightvision in cameras, and you can definitely see it in cameras that have it. The brighter the light, the more the camera can see in pitch dark.

In a fully dark room, once your eyes adjust then this would work. The lighting it very dim. Sorry I cant give you an empirical measurement in lumens.

Yes, I use them for outdoor lighting. Takes about 2-5 minutes to get to full brightness depending on the outside temp.

In a pinch, yes you could use them. I haven't been outside at 430am but they are bright when I have seen them at midnight.

I wouldn't think so. While it's a bright light, it's not "focused" so it's kind of diffused. I can see using a dimmer though if you want a night light effect. Really a neat light.

Well sure, you can. But I've found that this LED bulb isn't as bright as a standard bulb. I wouldn't try to read by them, but they do provide enough light to see by. And they should last a long time!

I do not think so. They are decent as far as solar lights go, but I would keep them within ten feet of the object to be illuminated.

I believe you can use AAA's but using those will deminish the brightness considerably. And it will use them up very quickly.

I don't use dark field viewing as a technique myself, but I have used it years ago in college. I don't think the light source is bright enough for dark field viewing. Sorry I can't be of more help.

First of all, that is not at all the use they were designed for. I suppose it could work, but the specs say the batteries last up to 40 hours, so if you used the lights much at all, you would be changing the batteries quite often.

It's possible but I don't think it's a good idea. The light can alter the way you see light and may be dangerous.

Yes it can, but at a reduced light intensity. Optimal brightness is at 11.7 vdc and they are very bright.

I use them for utility lights on the back of my truck. They are not very bright and might not work well for fog lights

I use them to shine inside my display cabinets in my shop, although I think I'd like one to use on my bed headboard for nighttime reading. Can't say exactly how wide of an area they illuminate, but I love them in the context of highlighting displays. A full sized, 60 watt spot would be just too much.

I have not had to use them as of yet. If you are using them as lights in a dark area or tent - you should probably have spare batteries around.

No, I do not know how to use as a strobe I only use as light. Could you please show me how to use as a strobe?
