Foot Candles of Standard Source4 Conventional Ellipsoidals (750 Watts)

That info will differ depending on which brand and voltage rating of the lamp, and what lens tube you're using. I would suggest checking out the MyETC Photometrics app. It's a free app, on both apple and android. You can set your specific lamp and lens tube and the app will feed you your photometric data.

Thank you
