The bulb is a replacement for my aging 18V Ryobi cordless flashlight. The battery lasts MUCH longer with LED technology than a standard bulb. The light it emits is tinted slightly green. yes green It's moderately bright - about as bright as the original. The light pattern is a circular ring (likely from a flashlight reflector lens) that has an effective range of about 60 feet. After that, the pattern deviates too much to be usable. As a slightly cheaper but energy efficient replacement, this is acceptable. I'm not thrilled with it, but it will be a bit of an upgrade. Would I buy it again? May be.
