The Chimera Kit is a combination of several products--for much less than if you bought everything a la carte.A 2kw softbox (with speed ring) and the Triolet continuous light fixture (with a 1000W bulb) form the core of this kit. The softbox is designed for use with a hot light but can be used with flash as well. With a silver interior intended for the heat of a continuous light, the Small Video Pro Plus 1 is ideal for work in small spaces when medium soft light is required.The 36 x 42" size is lightweight and portable. The "Plus 1" designation means the front face of the softbox is removable--Chimera makes different strengths of diffusion material for front face applications. The softbox comes with a one-stop diffuser, (hence the "1" designation). Purchasing the 1/2 and 1/4 grid cloths separately would allow for more light transmission and less softening of the light. A fabric eggcrate light modifier that attaches to the front of the softbox, directing and narrowing the beam (to 40°) for more control, is also included.This fixture is equipped for 120V AC operation. It will also function with 220-240V AC with the appropriate bulb and plug adapter, available separately.
