Last night while out on a night biking trip I took some light comparison shots. The three shots were taken at f/5, 3", @ISO200.
I'm running a pair of Hella 500FF's in the grille and a 20" Rigid LED on top. Here are the differences:
Halogen bulbs - 3,300 lumens 110 watts total
Ridgid LED 20" E-Series:
LEDs 7200 lumens, 78 watts total
High Beam + Hella's:
High Beam, Hella's, and Rigid:
I've got some more parts to throw on so I'll keep updating...
