Capture extreme close-ups or portraits with the VM-160 LED Macro Ring Light from Bolt, which features eighteen high-output LEDs with a guide number of 21' / 6.4m at ISO 100. The light features six levels of brightness adjustment from -1.5 EV to +1.5 EV and the continuous light source helps you easily see the effects of the lighting as well as enable use during video. Four clip-on diffusers are included to further adjust the quality of light from the ring light: clear, frosted, amber, and blue. Users can set the light to illuminate from only the left or right side for added dimensionality when shooting. Additionally, to help conserve battery power, the light can be set to work in flash mode, which will turn on the light for approximately a half second each time the shutter is released.
