Used in my home office as a reflector for online video conferencing. It's a good light and it's nice to have two-tone dimming + light filter to get a nice white balance, but the battery just doesn't match. It lasted about 55 minutes of an hour-long presentation before he died, and there wasn't even a full brightness light. I will continue to use it though; Maybe the battery just needs a full cycle of 100% discharge and recharge? UPDATED (June 2nd) - Yes, all I had to do was do a full discharge/charge cycle. Now I get about 90 minutes on a full charge. So upgraded to 5 stars.
