There has been a small amount of interest by some in the LED forum in the Epieon LED replacemnt bulb for PR style lights. I took some beamshots at 5 feet against my ceiling. On the right of all shots is an Arc LSH-S with a fresh 123a battery for comparison. On the left in each shot is my Mag 3D loaded with the standard bulb, then the Epieon. Top 2 are with some 6 year old used batteries removed from a radio, the bottom photos are using fresh D cells.
Old Batteries
incandescent.....................................................Epieon
New Batteries
The auto exposure makes the side-spill of the Epieon disappear, but is extends well beyond the frame of each photo. The stock mag bulb's sidespill just disappeared to the eye when the Arc was shining alongside. The stock bulb was actually more yellow to the eye, but the color is pretty much true for the LED beams.
The upshot is that the incandenscent bulb is dimmer with fresh and much dimmer with partly discharged batteries. The Epieon was not very different in brightness with either set of batteries. Based on a run-time test with old batteries, I would estimate the a 3D mag would run more that 10 days continuously on fresh batteries (I had usable light after 5 days using old batteries with my test, and it was still as bright as an Arc AAA).
This is using a 3-cell Epieon, which in theory will give the best brightness for the 1W High-Dome Luxeon Star LED.
