With a new seller online, there's a huge price drop on the 312 Bi-Color LED video lights. Falling approx. $80 dollars off from the normal pricing, this is an awesome light to use both on and off camera. Come to think about it, this is probably the largest 'on camera' LED Video light - and it's color adjustable. To get the most flexibility on this large light, don't forget about the Variable Friction arms.
Unlike the Socanland 277 LED, this one can adjust and mix between 3200K-5600K, and comes with two Sony compatible NPF550 batteries + charger + Carrying Case + Metal Ball Hot Shoe mount + Diffuser Panel. The lowest price i've ever seen it in the world, no excuses, says a few available. Take a look at the video review above, and find it below.
Not quite ready for the big 312? The smaller 144 Bi-Color LED Video light from the same manufacturer uses only one Sony style battery (below).
