M2-50 Direct Drive SST-50 M2 Head: in limited production

[Noctis]

Maybe DMM issue, not wanting to read closer to 5A's? Which DMM you using?

Bill

I suppose you would call it a "cheap" DMM from the RatShack.

On the other hand, it reads my regulated SST-50 from Nailbender at around 2.8A, my M61 at about 0.88A, and my SST-90 Direct Drive at 4.5A

I'd say it's fairly accurate, but perhaps the discharge ability of a single AW 2600mAh cell was overestimated? My SST-90 Direct Drive would give me similar readings using that cell.

You'll need to use some very stout leads to get a decent reading with these high current, low voltage setups.

The meter quality is probably fine.

Even my standard fluke leads will read low on these types of units.

Try some 6 inch long 12Ga. leads.

These will pull about 5 amps from a fresh AW 18650 2600 cell.

Make sure the shelf in your hosts head is clean for good contact also.

Which part is the shelf?

The part that makes contact with body, flat part.

anyone got lux please ?? :wave:
It could be my new small king of the throw....

 

[ElectronGuru]

Approximately 10,000 lux at 1M

Now see, that just sounds a bit off on the lux numbers.

Dereelight DBS_____Dereelight MC-E__________2 AW 2600mAh _________ 470.8 ______ 1 sec_______417______10,425___
__________________________________________________ _____________ 420.8_______30 sec_______________________
_______________________2.1A driver Stock ______________________________________ 414.6_______1 min________________________
__________________________________________________ _____________________________406.9_______2 min________________________
______________________________________________________________________________402.3_______3 min________________________

BigC tested the Dereelight DBS with an MC-E drawing 2.1A at about 10425 calculated lux at 1m... unless his math is off?

Night testing wasn't conclusive, as I suspect the neutral tint makes it slightly difficult to make out the beam against the ambient lighting. Seems about as bright as my SST-90 in a ceiling bounce, it leaves a "flashing" spot in my vision further away from the wall than my 90, and my xeno lamp seems just as bright when I point the beam inside.

So it might just be a tint thing.

Could also be the DBS has a bigger reflector, thus providing higher lux, which is not to be confused with flux.

The DBS is a purpose built thrower with a larger deeper reflector with a smooth finish.

Indeed, that's more un than scientific... :candle:

Perhaps it's me, but I couldn't say whether you use an M2-50 or a stock SF light, because you have no idea of the sizes of the things you illuminate, nor the distance they are away. The fire could give an idea, but as it's fire, it also emits light and disturbs the beam and the camera.

Nice try though! :wave:

Interesting. Would have been more interesting if you had narrated the film, so we have an idea of distances, what light you were using (yes I know, the M2-50, but...), etc.

Guys

It was something I did for fun. No way I was comparing the M2-50 to anything. I had amazing flashlight / my Nikon digital camera and free time....lol...

As I stated it was NOT scientific in any way shape or form....

I love this flashlight - its the brightest light I own so far - the tint is amazing.

I enjoyed the video. :thumbsup:

It was quite impressive how you started that fire by pointing the M2-50 at the ground.

First page of this thread has a warning to that effect....:devil:

Me too, but I'm a sucker for bright lights.

 

[Noctis]

I take it there are no plans for more of these?

 

[jamesmtl514]

I'm good for this. Mounted on a C2. Ceracoated White with the Ti ring.
please advise on final price.

These are currently in limited production. That means small, infrequent batches.

The M2-50 is currently where the Triple was last year. Production is in the pre planning stage and its design can still change.
