Ideal for use as a small unit but even better used as one of up to eight flashes configured as a ring flash for small objects via the appropriate accessories, the VM-1010 TTL Macro Flash from Bolt has a guide number of 33 and a color temperature of 5500K. The head also has an LED modeling light with an accuracy rating of CRI90 that means that you can also use it for video. The VM-1010 has a built-in wireless receiver that operates on the 2.4 GHz wavelength and accepts signals from a VM-1020 transceiver to trigger it and vary the power at distances up to 328'. The VM-1010 has output that's variable from 1/128 to 1/1 in Manual Mode and ±3 stops in TTL. It runs on two separately-purchased AAA batteries and comes with two types of diffusers and a 9-filter color gel kit for creative expression.
