GVM PROBD25R Light Stick LED Wand is a powerful Light source and fun to handhold for spontaneous effects as well. The light's 300pcs beam spread also makes it a natural for use as a side light, accent light, or hair light. The Stick's LEDs have color that's variable from 2700 to 10000K to meet ambient conditions, match other fixtures, or just for creative effects. Its high CRI of 97 is an indicator of precision in color rendering. Light intensity is conveniently variable too, and there's a downloadable app that allows wireless control of the Light Stick with a smartphone. The Light Stick LED Wand can be powered by a separately purchased AC adapter, or you can run it on the included NP-F750 li-ion battery for total freedom of movement.
