Today I got a Luxi Light meter and to test it I decided to measure some light bulbs against a Mole-Richardson kit I have out for a documentary I’m working on (http://bpmdocumentary.com/) So here’s the results that I got at 6ft, 800 ISO, 1/48th Mole’s Tweenie @ Full Spot f/22.6 Tweenie @ Full Flood f/12.1 Betweenie @ Full Spot f/20.2 Betweenie @ Full Flood f/11.3 Mole 800w Soft with Eggcrate f/4.8 Mole 800w Soft without Eggcrate f/5.7 Light Bulbs in Scoop 100w LED with umbrella f/3.4 100w LED without f/4.5 300w Photoflood with umbrella f/4 300w Photoflood without f/5.7 500w Photoflood with umbrella f/8 500w Photoflood without f/11.3 While you may think that something like a 300w photoflood is enough because you could close down to f/5.6, if you want diffusion, there goes a stop. If you want a gel like CTB, that might cost you another stop of light and when you go to a wide, you’ll probably need the lights furtherer than 6ft way. And all of a sudden your left with only f/2 of light. However using something like a Betweenie offers you lots of options with barndoors, spotting and flooding. If only I had the money….Film Life. Oh and the Luxi Meter is pretty sweet.
