Has anyone estimated or measured the wattage for each output level? For example 1000W for Turbo, etc.

cool i'll see you when you get there

I estimated it used about 1200 watts for max output here.

This is a very hard light to measure current from. You can’t do a typical tail cap current measurement. You can run wires between the battery pack and head, but its difficult and the wires resistance effects the results. You can power the head with a bench power supply, but that will not give accuracy either.

Ya, not easy to find a 1000+W power supply either.
I am thinking it should be FET type of driver in the MS18. Wonder anyone change the FET to lower resistance type. But the battery would already be the limiting factor.

I’m not clear on the driver design because someone mentioned it can do steady output levels on the lower brightness levels. It does use at least 7 (possibly 9) of the Goford G16N03A mosfets (30v 16A). Maybe it is a standard PWM FET type driver?

The steps in this test make me think it’s not the regular FET driver design. Usually a FET has smooth steady drop due to battery voltage dropping.

Then in this longer running test you do see a steady output drop as if the batteries are draining. It still has these small steps, though. I don’t know enough about driver design to explain these small steady steps.

I don’t see any inductors in the driver so I don’t think it’s a Boost or Buck design.

I dont know if it´s 1200 Watts but it´s interesting what effect the outputpower has on random stuff.
I found this video on Youtube

Is there currently a more powerful flashlight on the market?

Late to the party, by quite a margin, but I’m in all the same!

My lightbox is calibrated to have no multiplier and have the meter show actual lumens, verified with a set of Maukka’s lights. I also have a 6” adapter that has a 1.292X multiplier. The 40T cells this light is said by Imalent to utilize power my new light to a start value of 75,700 lumens sitting on the rim of the tube. With the adapter, however, it figures out to 58,398. The reduction of the adapter apparently influences the reading.

This light IS amazingly impressive though, to be certain. Pricey, yes. Noisy, yes. Hot, oh for sure! But it’s OMG retraction ability is second to none!

Ok, I got to thinking about how the light fits the light box and made a small change. My light box is a 4” Industrial P trap, there is a 90degree elbow that has a glass shelf the lights typically sit on, but the MS18 is large enough that it is the same size as the sch 80 fitting. This means the light doesn’t sit on the glass but rather 1 3/4” above it. So I cut 3/4” off the top allowing my usual foam to fit flush. This brings the MS18 closer to glass level. And now I get a start reading of 84,300 lumens.

Now I am considering cutting the rest off such that it will be flush with the glass, then this big light will be tested from the same glass level surface as all other lights, including the Maukka calibration lights.

Wonder if that will indeed show the 100,000 lumens advertised?

Edit: Cutting my lumen tube so the glass is flush I got 92,800 lumens. I put a 16 ga. spring bypass in the head and now it shows a cold start, fresh charged, at 95,400 lumens. Drops down into the low 70’s within 23 seconds with a steady drop as it heats up and the cells sag.

Took the MS18 out to the lake, covered 100 yds to the post line beside a road and out to a body of land to over 480 yards. That first hundred yards is intense! What surprised me is the beam visible in the air, a decent parallel column of light that pushes out pleasantly far!

Almost 80 degrees, 21 mph winds gusting to 33, all kinds of stuff blowing across… not a great night for beamshots but interesting all the same.

Excellent beamshot! Looks like daylight!

Hi.
I have received a newsletter from Imalent,saying about a NEW R90TS with heatpipe.
Have you any idea of this?

cant it run at fullpower with the fan on before dropping after around 20 seconds ?
