Manfotto announced the Spectra 1×1 LED lights earlier this year and had the new units on display at NAB 2014. The Spectra LED fixtures offer a CRI>90 and are flicker free.
The lights are fully dimmable from 0-100% and are available as daylight balanced or as a dual temperature model that allows you to toggle between daylight and tungsten color temperatures. Spot and flood models are available for the daylight balanced lights, while the dual color model has a flood throw.
They provide an equivalent output of 500w tungsten fixtures drawing just 40w at 24v.
The lights can be powered by an included external AC adapter or can by batteries with an optional adapter.
The Spectra 1×1 models retail for $999.99 for the daylight models and $1789.99 for the dual temp model. However, all are currently on sale at B&H for $779.99 for the daylight balanced models and $1079.99 for the dual temp model. You can find all of them here at B&H Photo.
