Headlight Experiment
This evening I ran an experiment. I added two MagicShine lights to my Borg in addition to the existing Cycle Lumenator:
These are the 1,000 Lumen rated MagicShine Cree MJ-808E XM-L LED lights with a "Y" cable and a four cell 18650 2S2P battery. The rating is optimistic of course but the actual output is likely around 600 lumens per light, but more important is the pattern.
I flipped the Cycle Lumenator upside down and made room for the two MagicShines on top of the handlebar. The curb side MagicShine points slightly away from center, so it lights up the side of the road nicely (where the deer was), the other MagicShine is fairly well centered.
When I left work I fired up the Cycle Lumenator first. Lots of light as always, a very broad and soft pattern. Then I fired up one MagicShine, and it punched a hole right through the Lumenator, significantly brighter in the central cone of light, reaching out much further. I fired up both MagicShines and ran all three lights for most of the commute home. The Lumenator providing close in light, and the MagicShines reaching out. Cars that would pass me on the highway would light up the pavement ahead about the same as my lights. This was a MAJOR improvement in long range light which is very helpful for my commute.
The drain was significant on the battery pack with both lights drawing from it. About 3/4 of the way home both indicators turned red so I turned off the curb side MagicShine to conserve the remaining battery, and the indicators recovered to amber. Even one MagicShine was a significant improvement over the Lumenator alone. The Lumenator is a great light, but the pattern is not what I need for dark highway bike lane commuting at 28.
I'm thinking that a light bar with several smaller adjustable LEDs that could be adjusted to make the desired pattern, combined with a high/low beam switch might be the ticket. Perhaps two lower powered wide angle optic equipped LEDs aimed downward for close in lighting, and two high powered narrow optic equipped LEDs aimed out farther for the high beam long range lighting, using TIR optics to control the light pattern.
