Popular bulbs current draw; SF & other brands, incl hotwires

[igabo]

Someone should sticky this..

And, sorry to hijack the thread, but how's the brightness on the high efficiency
DRB-9VHP compared to the regular high pressure version?

[rikvee]

Hi Igabo, the HP G90 is rounder and a tad whiter than the P90, the DRB-9VHP I have never seen.
Perhaps someone can sell me two of those, I can do CC Paypal....

Still need the figures on these ones:

- Surefire MN 11 9V M3 - ?
- Wolf-Eyes 12V D36 - ?
- Wolf-Eyes 12V M100X - ?

You're welcome

I went and dug up my old notes on Welch Allyn bulbs, using specs culled from their website. I built my own list for planning purposes, thought I'd post it here. All info is from WA and not my own measurements.

Thanks again, Kevin, list is a bit longer

[KevinL]

Oh yeah, I was reading the list and noticed that your MN11 had a question mark next to it - I thought that one had already been answered, sorry to make you do so many edits.

Surefire MN 11 9V M3 - 2.50A, I just measured on 2x18500.

That should be all the lights I have, the rest of mine are LED/HID with what we affectionately term "non-linear characteristics" (in other words: it can be all over the place )

Your list is an excellent resource.. I always thought the Surefire high output lamps were more in the region of 2.2A, but it seems that measurements on the list and my own numbers indicate that they are all around 2.5A.

Just a humble suggestion.. they call 'em bulbs too, out west.. maybe put that in your subject title/sig so that you get more hits? I'm familiar with the globe reference, having worked with Australians, but not many others are.

[rikvee]

Hey, thanks again Kevin "endless edit'' is my middle name, I love it!
- changed title to global speak; I am originally Dutch, have lived in the USA as well, so to tell you the truth, I actually called it globes 'cos I thought that was "American", I already happily miss-spell words like "color" (colour) and "aluminum" (aluminium) for the benefit of the major readership of this forum
- my own reason for this list is for the purpose of using Li-Ion batteries, in fact, is this list right, and could you tell me which other WA bulbs would work with Li-Ions?

ROP 3854 6-7.2V low 1.90A - 2 Li-Ions >950mAh
WA1165 6.0V - 1.87A
WA1306 ? - 3 Li-Ions >1000mAh
WA1319 4.8V - 1.92A
WA1331 9.6V - 1.93A - 3 Li-Ions >1000mAh
WA1318 9.6V - 1.93A - 3 Li-Ions >1000mAh
WA1166 11.6V -1.97A- 3 Li-Ions >1000mAh
WA1274 7.2V - 2.77A - 2 Li-Ions >1400mAh
WA1185 9.6V - 3.15A
WA1164 6.0V - 3.28A
WA1111 6.0V - 3.35A
WA1160 5.0V - 3.45A
WA1183 4.7V - 3.85A
ROP 3854 6-7.2V high 4.15A - 2 Li-Ions >2100mAh

[KevinL]

Your list is mostly correct, however the WA1166 and 1274 are not optimal for lithium ion drive, because lithium ion voltage tends to sag heavily under load, and you won't get the best possible brightness. You can do it, just that it may not be as bright.

I think it was Icebreak who suggested the Mag85 LE, which is 1185 on 3 li-ion cells of 1000mAH and up. Sounds good to me.

The WA1111 is ideal for 2 li-ion, of 1500mAH and up. While searching for a bulb for my Mag 2C lithium ion project (2x18650) I originally considered the WA1111 until I realized the ROP bulb was not only better, it was more convenient, coming in a PR base. So this one can be done, but I prefer the ROP bulb if my cells can take the pounding. Same rationale why I didn't use the WA1164/1165 either.

1319/1183 are good for 4 x NiMH, possibly 4 high current NiMH AAs in a bored and cutdown 1D Mag. This has already been done.

[rikvee]

Beauty Kevin!

If the WA1185 bulb likes to draw 3.15A, in order to not stress the batts above 2C don't they need to be at least 1600mAh each?

[KevinL]

Oh yeah, mistake in my calculations (see, always double check.. glad you did ). I generally go for high capacity 18650s for the superbulbs anyway.. all 2000mAH and up

[rikvee]

'found the Welch Allyn website, that pretty much lists all the WA bulb specs,
I guess I'll leave my little list up for a quick reference and Li-Ion compatibility.
Anyone who can help me with the current draw on these:

Wolf-Eyes 12V D36 - ?
Wolf-Eyes 12V M100X - ?
SF MN 60 M4 LOLA - ?

Carley 928 - ?

Superstinger - ?

[InfidelCastro]

How about the Digilight DRB-6VHP?

I've read .8A like it's 9V big brother. Is this true?

[InfidelCastro]

Btw, anybody have a DRB-6VX2 lamp?

It's the one in the Digilight 1000 series of flashlights. I've never heard it talked about here before, but the specs are better than the MN03 if they are to be believed.. 70 lumens for 90-120 minutes. Looks like they would fit in the Surefire E-series of lights, but I don't know for sure. It just looks that way.

I wonder what the current draw is and how the beam compares to the Surefire MN03?

[rikvee]

Thank you, InfidelCastro, good question!
I would just like to be able to buy a guaranteed superbright, super efficient globe like that.
I still think they (the DigiLight DRB-HP Series) are a misunderstanding and actually do not exist, a combination of mis-interpreted specs and hearsay......

DigiLight DRB-12VHP - ?
Wolf-Eyes 12V D36 - ?
Wolf-Eyes 12V M100X - ?
SF MN 60 M4 LOLA - ?

[RowdyOne]

More 2 cells lamps

Wolf Eyes 3.7v on an AW 17670 is 2.08

Wolf Eyes 6v on the supplied Battery Station CR123s is 1.2

Both lamps from Mike at PTS within the last 2 or 3 weeks.

[rikvee]

Thanks Rowdy, are both the 3.7V and the 6V called D26 as well?

[rikvee]

still looking for the current draw of these ones too:

WE 12V D36 - ?
WE 12V M100X - ?
Surefire MN 60 M4 LOLA - ?

[rikvee]

New title, tidied up list on page 1 of this thread.

Any corrections/additions welcome

[nzgunnie]

I just got an MN60, it's drawing 1.48 amps on 4 batterystation 123s.

MN15 is drawing 1.05a from a pair of AWs 17500s

Digilight's 12v xenon (not marked HP - don't now if that matters) is drawing 1.26a.

I have a Digilight 9v, although apparently not the HP version, it's drawing 1.12 amps on 2x17500s. It is whiter and a bit brighter than a P90. Digilight are going to send me the HP version when they have it in stock.

[rikvee]

Thanks nzgunnie

Once I can order a guaranteed .8A at 9V Lamp assembly that fits Surefires
and is brighter than my 1.2A G&P lamps, I'll have 4 meself ...........

[Paladin]

SF N62 fed by slightly used SF 123's(four) pulled 3.5 to 3.7 amps.

Laser Devices OP-9 fed by three cells pulled 1.35 amps.

FWIW I measure the tail cap current of most new lights, so down the road I can have a feel for when to change the batteries, such as at 80% of initial, fresh cell current draw.

Paladin

[rikvee]

Hi Paladin

is the N62 the M4 style lamp that is only to be used in short burst of less than a few minutes?

I think I read somewhere that CR123's shouldn't be expected to deliver above 2A, while the entire Surefire HOLA range, including the P61 seems to ignore that idea......

[rikvee]

dreaded double post; CPF is as slow as wading through mud right now.....

Hi Paladin

Yes, but I was under the impression bursts needed to be limited to around a minute, but self-impose about a 30 second maximum.

I agree wholeheartedly that 3.5 A. is way beyond the CR123 design limits. And four cells in series probably exponentially increases the potential for a bad cell to die, and then explode, from the other three cells driving current thru it. Nothing but SF brand will be used in it, and that will NOT be very often since the M4 is overkill for 99.9% of my lighting needs.

I just wanted a "Lion Light" clone for the off chance I might need "redneck night vision" capability while shooting at night. FWIW, had I known before how well the 9P/KT-2/MN16 throws I would probably not have bothered with the M4/N62.

Paladin

[rikvee]

"redneck night vision" , love that!

yup, the KT/MN16 combo out-throws my WA1274 on a smooth finish metal Mag reflector, very oval beam though, the N2 is nice and round and draws less then half the amps (1.21A), so it probably lasts twice as long....

Does anyone know the current draw for the M3 LOLA, the MN10?

[rikvee]

Should there be any additions to this little list at the bottom of page one?

Hi rikvee

I run my Osram 64275AXs in a direct drive 6C Mag and regulated @7.0V in a 3p2s-Li-Ion M6 if thats any use

Cheers Pete

Thanks Pete,

what batteries are in the 6C, and is "3p2s-Li-Ion" two blocks of 3 parallel R123's in series?

My pleasure, cue003!

Thanks Lunarmodule, have put them in
Do you think the varying results (as in MN16 M3T HOLA- 2.54-2.65A) are due to individual bulbs, or the state of the batteries?
