The mounted Tiffen 6" Round 81EF Light Balancing Filter helps to decrease the color temperature by 650K in order to warm the image slightly in order to match the color quality of illumination. When using an 81EF filter, you will be able to attain 3200K balance when the prevailing light source is 3850K. The warming 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 and grinding flat to a tolerance of 1/10,000th of an inch.

Warming Light Balancing Filter    Less 650K to Convert 3850 to 3200K    ColorCore Technology

Light balancing filter decreases color temperature and provides a warming effect.

Subtracts 650K in order to attain 3200K color balance from 3850K illumination.

Filter factor of 1.5 requires a 0.6-stop increase in exposure.

Q: 10. What is the Guide Number for this flash? Or what is the f-stop at 10 feet at full power at ISO 100?

A: Unfortunately, there is no conversion to convert watt-seconds to guide numbers. A watt-second is a measurement of energy, measuring how much power (watts) is delivered in one second. A guide number is simply a tool to allow you to calculate the working exposure you may use from a flash with a set reflector degree/beam angle when the flash is on-axis with your subject. The issue is the guide number can vary widely from the same flash head if you use a different reflector size or if the flash has a zoom head. The exact same flash with a zoom head set to a telephoto zoom setting will have a much higher guide number than the exact same flash with the zoom head set to a wide angle setting. Hot shoe flashes have built-in reflectors and are designed to be used as-is (even though they can be modified). Studio strobes (such as the Interfit Badger Unleashed strobe head) are designed to be modified; they typically do not have built-in reflectors, and instead have a bare-bulb design. A reflector is not included with the purchase of the Interfit Badger Unleashed​ strobe head. The exposure measured at your 10-foot distance at ISO 100 would vary wildly depending if you used the light unmodified (in which case it would have a much wider 180-degree beam spread compared to a hot shoe flash), versus using a 7-inch reflector, versus using a magnum reflector, versus using a 22" beauty dish, versus using a softbox/umbrella, etc. As such, when comparing studio strobes, it is easier to compare the maximum power output from the unit with the output of other studio strobes rather than to give a guide number to calculate exposure which will vary depending on the modifier used on the strobe.
