Okay... as promised, some beam shots and numbers for the newly arrived M61SHO. As I've said previously, I only own warm/High CRI Malkoff's so I don't have a good tint comparison, but the shape of the beam should be apparent. Also note, I lent my camera to a friend on Friday and forgot to get it back so these are cell phone pictures :sick2:. Wall shots are white balanced to "florescent" which was the best of my options and taken at 100 ISO.
First, for comparison:
M61 219 in MD2 with 2 x CR123a
M61W (3700) in MD2 with 2 x CR123a
M91W in MD3 with 3 x CR123a
and finally, M61SHO in MD2 with 2 x CR123a
I also took some very quick outdoor beam shots but again, this needs to be done by someone with a proper camera. Kept the white balance at "florescent" but bumped ISO up to 400 (in retrospect, should have been higher).
Same configuration, same order:
M61 219
M61W
M91W
M61 SHO
And for the numbers...
These are 1 meter lux numbers taken with my lux meter at the brightest part of the hot spot about 10 seconds after turn on. Note: I do not have a lab setup, these numbers should be considered only as relative to each other.
M61 219: 1760
M61W: 2050
M91W: 2300
M61 SHO: 5870
oo:
And just for kicks, I took a ceiling bounce test to compare my M91W with the SHO:
M91W: 38.4
M61SHO: 40.9 (a hair over 6% brighter)
Impressions are as follows:
I didn't know what to expect in terms of the beam profile. In my mind, it could have been a wider or narrower hot spot than the M61. If the pictures are any indication, the hot spot is definitely larger, but it is also noticeably more intense. It's tough to speak about the spill since the higher intensity of the hot spot diminishes any perceived increase in the brightness of the spill, however I suspect it is also significantly brighter.
In general, the beam is flawless. Very smooth transition from hot spot to spill, no rings like the M61 219 or irregularities like the M91W. It's as if the reflector was made for the LED. I am very, very happy with the performance of the light, especially on 2 x CR123a. The ability to run this fully regulated in an MD2 is awesome. The M91W runs at almost full power on 2 new cells but it eventually starts to taper outside of regulation.
I'm clearly a warm tint guy, but the tint on this is actually very nice. Quite obviously cooler than the warm drop ins but not a hint of blue. Just bright white. That said, I will be first in line for an M61 SHOW :devil:
Also, I have no idea what this would look like but we need to get this thing in a Hound Dog head. If it throws half as well as I think it will in that big deep reflector, the potential for a shorty 2 cell pocket thrower with Malkoff toughness is extremely enticing.
Hope this was helpful.
Cheers!
