Smartphone cameras are getting better in low light shooting but they still have too small a sensor to capture crisp photos and videos in darker conditions. A portable light like the Iwata GL-01 can help improve the quality of your work. It comes with 117 LED beads and adjustable color temperature 3000K-5500K.
The Iwata GL-01 video light has a 2300 mAh battery and lasts up to 1 hour on high power mode. It has a 1/4 screw hole, so you can be used with your rig and selfie stick. The light has a 120-degree beam angle. It weighs only 136g.
