he Compact Magnetic RGB LED Tube Light from Ulanzi measures only 3.9 x 1.6" and is compact enough to use handheld. It's also magnetic and can be used attached magnetically to something, and it features 1/4"-20 mounting threads for alternate mounting options. Additionally, it has a nonslip silicone mat on the bottom so that you can simply set it down on a tabletop.

The light has a CCT mode offering a wide 2500-9000K color temperature, and an HSI mode where you can choose from the gamut of RGB colors. It also offers 20 built-in special effects, such as strobe, candle, and fireworks. Make your selections using onboard controls and a color LCD display. The Tube Light operates on a built-in 2000mAh battery that runs up to 90 minutes. The battery is rechargeable in about 2.5 hours, but the light can be used while it's recharging. A USB charging cable is included.

The integrated magnetic mount allows you to attach the light to most metal surfaces. Multiple units can be neatly lined up magnetically for a brighter output. The 1/4"-20 mounting threads, one on each end of the light, allow mounting on a wide variety of common supports, including mini tripods and articulating arms. The light delivers an output of 700 lux at 1' distance.
