Hi all,
I'm trying to pick a small (4D or smaller) high power light. I'm looking for at least 1000 lumens output and 45minute runtime or longer. Is there a ROP or MAG85/74/? setup that meets this set of requirements? Thanks!
I see others are addressing the lumens questions. Torch lumen or bulb lumen. Because as long as we stay relative, look at the WA1164 on 9.6 volts or the Phillips 5761 on 7.2 volts because both in typical configurations have higher lumen outputs than WA1185 solutions. Torch lumens compare respectively 1185 @ 800 L, 5761 @ 896 L, and 1164 @1015 L. The calculations are from the WA equations imbedded into the HotRater calculating spread sheet published by AWR. You can build a 2D 1164 or a 2c-cell 5761. The 1185 was out there first and hence its proven popularity and is very efficient for output, since its origins other solutions have been developed.
There are great threads on all of these, use the search feature and search key words: 5761 and 1164 and lookout, the returns are great for 1185, m85, etc. Have fun, so many choices, so little time.
