The Tiffen 138mm 82B Light Balancing Filter helps to increase the color temperature by 300K in order to cool the image slightly in order to match the color quality of illumination. When using an 82B filter, you will be able to attain 3200K balance when the prevailing light source is 2900K. The cooling effect of this filter requires a 0.6-stop increase in exposure for normal results.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 4. I recently purchased the Dracast LED500. I'm looking for a solution to diffuse the light and also protect the bulbs. The way that the light ships, it does not come with any glass or plastic over the bulbs. This product looks like what you would need to start with, but once this product is purchased, what's next? Where can I get drop in diffusion for it?

A: That light should ship with a clear LED board protector in it already. There are drop-in filters (both diffusion and CTO) available, which need either a filter frame or barn doors to be able to fit correctly. // Also, if there are any other technical or product related questions, feel free to contact us directly at any time at support@dracobroadcast.com.
