Ok I just got 3 lamp assemblies in.. all D26
3.7V HO-4 (*tested 1.8A)
9V EO-9 (*tested 2.0A)
9V HO-9 (*tested 1.6A)
before I begin I want to say that these lamps have a very FAT shape and do not fit properly in some flashlights. my ultrafire does not support these lamp without major modifications. (been grinding away material for awhile now to make room)... so if you have an ultrafire or similar light, you might want to take into consideration that these may NOT fit. (EDIT IN, CORRECTION: read below for more details on this, some ultrafires fit, some do not)
I'll probably take beamshots later tonight or tomorrow night if I have time. my initial impression of light output is that the EO-9, supposedly rated 380 lumen's, is about 60-70% as bright as the P91. (comparisons done on pair of 17670s). I was hoping this would be brighter, but oh well.. worth a try...
the 3.7V appears reasonably bright, a little brighter than the stock maxfire lamp...
*just tested current draw... going to top batteries off for beamshots tonight. I think it is fair to say that these lamps, are proportional in output to their wattage when compared to other lamps, no magic pixie dust here, more power makes more light... The 2.0A draw of my EO-9 would put it at ~75% of the *power* of a P91(2.7A), They both run very similarly white off a pair of li-ions, suggesting that they are being driven into the same realm of efficiency.... using this simple method of comparisons on paper, we could also say that according to LFs measuring techniques, a P91 would score over 510 lumens. The HO-9 also appears to be right in the ballpark, appearing brighter than a 1.2A G&P G90, but of course- dimmer than it's big cousin. The HO-4, again, appears to be right in line producing an appropriate amount of light for the power consumption. The tight/smooth beams of all of the LF LAs is really impressive. LF has offered some great "sweet spots" for LAs IMO. niches that haven't been addressed by other brands. After playing around some more, I am really liking the beam pattern of the EO-9 when compared to the P91, I think I'll be willing to sacrifice some lumen's for this beam and longer runtime. I think I'll probably pick up an Ultrafire WF-502D to replace the older model that I had to really grind out to fit these lamps.
more to come later....
**BEAMSHOTS
*** really wanted to have a comparison of the LF EO-9 and the SF P91 that takes the beam profile out of the picture and really shows raw output. A ceiling bounce shot- with the picts taken from a different room through the door is great for this because it totally eliminates the beam from the shot. In each picture, the light is in the same position on a table back around the corner inside the room pointed straight up.
