Yes, low first is definitely the way to go with a non tactical drop-in. Also, and I don't know if someone has already asked the question but what happens if you use the LMH drop-in in an MD2 with a High/Low Ring? Do you get 6 Modes? Or does the driver interpret the reduction in current as a dead battery and it just doesn't come on?
Okay. No one could answer this question for me so I did the CPF thing and bought one so I could test it myself :devil:
Here are the results for all three modes with the head tight and loose using a two stage ring: (Please not these were not ceiling bounce measurements but rather measured at the center of the hot spot at 1 meter so this may actually represent peak intensity better than overall output)
Mode
High | Lux (Tight)
5200 | % of Max
100.00% | Lux (Loose)
83.1 | % of Max
1.60% |
Med | 1070 | 20.58% | 18.9 | 0.36% |
Low | 210 | 4.04% | 5.6 | 0.11% |
So it actually
does give you 6 modes. A High, Med, and Low, and then low low, low low low, and low low low low.
I got curious about whether the modes would work at all after the light dropped out of regulation so I tried it on a single CR123 reading 3.01 volts. Here are the results:
Mode
High (CR123) | Lux (Tight)
1330 | % of Max
25.58% | Lux (Loose)
16 | % of Max
0.31% |
Med (CR123) | 260 | 5.00% | 16 | 0.31% |
Low (CR123) | 50 | 0.96% | 16 | 0.31% |
So you do get modes when the head is tight, but you only get one output with the head loose.
Also, to give you an idea what to compare these lux numbers to, here are some other lights I did with the same setup at the same time:
Light
M61 SHO | Lux (High)
5900 | %of Max
113.46% |
M61 (XP-G2) | 4300 | 82.69% |
M61N (XP-G2) | 3100 | 59.62% |
MDC | 4200 | 80.77% |
The M361 is advertised as 400 lumens and the SHO is advertised at 385 but the SHO is measuring a little over 13% brighter so (assuming they're both using the same reflector and LED) something's wrong. But, it does perform measurably better than the M61 XP-G2 (about 18%) and it appears to be optimized for a single Li Ion so that's awesome.
One more comment on the modes. As others have mentioned, it's not, strictly speaking, a LMH. It doesn't
always come on in low. In fact, it only comes on in low if the last time you used the light you let it burn more than 5 seconds on whatever mode you were using. If you had it on for less than 5 seconds, it will come on in the next higher mode than whatever it was when you turned it off. Also, if you try to change modes too quickly by just light pressing the switch rapidly, it won't change modes. You have to wait just a fraction of a second after soft pressing the switch to press it again if you want to progress through the modes. You have to be pretty quick to trick it, but it happened to me a few times.
Hope this all helps!
