This 2-stop, 130 x 173mm FotodioX Soft-Edge Graduated ND Filter 130x173mm 2-Stopfrom FotodioX Soft-Edge Graduated ND Filter 130x173mm 2-Stopis designed for use with the Cokin X-Pro series or FotodioX Pro 130mm filter holder systems. It helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. Neutral density filters do not affect the coloration of the image and this filter provides up to a 2-stop reduction in light from entering a lens. This filter is made of durable, CR39 optical resin and measures 2.9mm thick. A plastic sleeve is also included with the filter.

Q: 9. Regarding the output of the light, how bright is it at its highest setting? For example, it is comparable to a 500w light, 650w, 1000w, etc. in terms of how bright it can get

A: Wow, one guy says 65 watt equivalent, another guy says 650 watt equivalent. What a difference! Here is the definitive answer: An old-school 750 watt Lowel Tota tungsten light puts out 2,700 lux at 3.3'. This light puts out between 778 and 865 lux at 3.3' (depending on your color; 5600K mode is brighter than 3200K mode). That's ~30% as much light as the Lowel Tota or the equivalent of a 220-240 watt tungsten light.

Q: 10. How many LEDs is in this?

A: Fotodiox does not list the number of leds but please note this light uses leds that are reflective in that they come in from the side.They will have less than the front facing type.
