What kind of light does a COB panel give?

COB LEDs are a flat array of many small emitters, so the light is broad and even rather than a tight hotspot. That makes it good for lighting a work area up close, less good for spotting things far away.

It takes three AAA batteries, and a set is included. The cells are replaceable, so you can swap in fresh alkalines or rechargeables instead of waiting on a built-in battery to charge.

Can it be used hands-free?

The wrist strap lets you hang it from a hook or loop it over your hand while you work. It is not a headlamp, so it will not aim itself the way a strap-on light does.

Does it have different brightness settings?

No. It uses a single push button for on and off, with no dimming or strobe modes.

No water or impact rating is stated, so treat it as a dry-weather, indoor and sheltered-outdoor light rather than something to submerge or leave in rain.

How does it compare with a regular flashlight?

A reflector flashlight throws a beam much farther. This light favors a wide wash of light for close work, and its rubber body and strap make it easier to hang and handle.
