10 gram USB light 200Lm

Are these flood lights? What kind of  switch? Different brightness levels?

does it only work when plugged into usb power bank?

a similar one at amazon “2 PCS Mini USB LED Light, 8 Colors RGB Car USB LED Interior Atmosphere Light, Adjustable Brightness Smart Laptop Keyboard Home Office Decoration Night Lamp, Car Accessories”

$8 for 2

that one requires a usb power bank

amazon has one similar to TTs

$8 for 4

the one on amazon doesn’t explicitly say it requires a usb power bank, but I infer that it does

it says the wattage is 2 picowatts

that can not be right, maybe 2 milliwatts?  At least they have a unit of power and not volts or coulombs or something : )

The only switch is on my battery bank. Or just unplug it.To get to $10 and free shipping, I did get a miniature floodlight with a switch. Multicolor lights. It was 2.3 oz. Not bright enough. I also got a duel floodlight that was decent. It was 2.5 oz. but the lights could be spread out or attach one while holding the other. I figure if you’re already carrying a battery bank, this may be enough. Save a gram by removing the cap.

I got the title wrong. It’s 10 grams.

The first light shown is a flood light. Rather blinding until I made an aluminum foil reflector. A piece of tape may work as well. I haven’t tried it. The dual lights worked well, though there was little advantage in having dual lights. The third light surprised me. Brighter than I thought. It has a switch for of/on, 8 levels of brightness, multiple color choices (all dimmable), strobe feature with choice of color(s) and speed. $7.00 and 65 grams.

These are great, Terran. So much lighter than lugging around a headlamp with a battery!

Now we need one of those flood lights in green or red to attract fewer bugs and maintain some night vision.

Not the all-too-common dim auxiliary red lights for camp — those are easy to find. I want one that is bright enough to see the trail — like 100 lumens or more.

These I don’t know anything about.

Red flood

4 Watts total (8x 0.5w) could be as bright as your other flood light. Cool.

Let’s see if we can build a better headlamp than can be purchased for any price.

I splurged on another $10 worth. Ordered a couple reds, blues, and greens plus a couple dimmer switches. Found a switched splitter on Amazon. That might be getting heavy though.

I ordered a few of these of different types to try out. At 10g, not bad as a back up. I currently carry only a RovyVon that I can clip to my hayt, weighs .6 oz

For the price they make a decent camp light. The weight is reasonable. A piece of duct tape on the back with some foil as a reflector to shield the eyes.

I like my tiny flashlight for cheap. It’s handy enough to make me want to get a better one. The RovyVons look like nice lights.

I’ve been trying out those little card shaped USB mini lights that weight 1g. They work great as a reading light in the tent and it’s bright enough that I could hike by it if I really needed to. I stuck 2 of them in my pack that I’ll carry as back ups now. I don’t usually carry back ups of anything, but it weighs about as much as a drop of water it’s a better “lantern” type light than my model of RovyVon.

I’ve also been experimenting with that 5g USB-C light from the OP. It’s bright enough to hike by also and while it’s not likely durable, it might make a good UL back up.

The clear plastic may get a bit wobbly, but it doesn’t effect performance.

Using Nitecore 6k power banks. Useful light about 25′. Ability to easily recognize objects about 60′.
