looking for ROP bulbs

[lctorana]

Being D size, and high-capacity, the bulb could be seeing as much as eight volts on initial power-on.

I recommend either:
a) switching to the 3853H, or using a 1274 in a bi-pin socket. These will give similar output.

b) sticking with the 3854H, but wiring a NTC into the circuit somewhere. Or even going with a soft-start regulator, but that's a comparatively expensive option.

Hey, THANKS for the advice. choices, choices. -i guess i was a little hung up on my lipstick red 6D Mag with a KD 8.3mm opening MOP reflector and pointy little 3854H bulb. -that was pretty BA :devil:. just downgraded that one to the 3854L for now until i pick up the 3853H. sounds like it will work.

fortunately, i picked up a second 6D Mag waiting on a KD SMO reflector which i want to keep in pristine condition and use with the 3854H strictly as a show off light (throw, etc.) think i'll try my luck with a couple more of those bulbs (any requests to swap a few 3854L with 3854H??). the very first 3854H bulb i had seemed to work fine. had it on for well over half an hour once and ran it fresh off the charger at least a few times. maybe a future upgrade to the flashlight is in check. hopefully it'll work again...

to add a note: i just walked into Radio Shack, and they were selling off their discontinued nicads for $2 a pack. (pretty darn cheap - couldn't pass that one up) anyways, i ended up with 8 C 2000mah cells. put 7 of them (along with the aid of a PVC pipe) into my 6D mag with 3854 low bulb and it handled it great right off the charger @ 9.4 volts (after 20 minutes of use the voltage was still at 9.0). very bright - i think around 900 - 1000 bulb lumens!

i even tried 8 cells @ 10.7 volts. i kind of new this would fry the bulb - didn't think that it would actually light up for a second like it was attempting to handle all 8 cells! -surely a tough little 6 volt bulb!!

Bumping an old thread, but are these still available? I am looking for them online but no luck - perhaps being in the UK is filtering out the places that sell them? Thanks for any help - I have a Mag that would really appreciate the 3854-L.

Last set I ever saw new in package was on eBay a few weeks ago. They were 3804 Big D bulbs for 6 D cell Pelican lights. Guess they were old stock or something.

I am not sure what the lumen specs are on the 3804, but the packaging says for 6 D lights.

I have some, though I will have to dig them out. I will check back tomorrow.

Thanks - all help or leads appreciated.

Pelican 3853 and 3854 have been discontinued long time ago.
Currently, I have some custom bulbs with spec close to what you need. PM me if interested.

3804 is designed to work with alkalines and current draw is too little than 3853-L

Looks like battery station still has 3853 bulbs...

They did not when I called them 2 weeks ago

 

[jabe1]

They were showing in stock, maybe they haven't updated their site.

Midwest case company should have 2 more, I bought 3 last week, they had 5 in stock.

HPX53 is only a 1A bulb, but it can take 2 off the charger IMRS and throws like a laser.

Is the OP still looking for them? where are you located?

I may have a bunch of these.

 

[saeckereier]

Strange to think that some day soon these will be pretty much impossible to come by.
I'll hold on to the two packages I have for my C maglite

 

[Greenbean]

Sad isn't it.

I have a new Mag 6D that hopefully will get some nickel metal hydride cells.
I know it's going to be a big heavy light, but it kind of sits on the shoulder easily, I still have to research from years ago which bulb is going to be the best to use in that, I think it's the 3853 HO.

I like the idea of almost 10,000mAh also.

Anyone who has 3854's they are willing to part with, please PM me.

Thanks in advance.

Minimoog has priority here re ROP bulbs.

LuxLuthor's incredibly useful data didn't include any service life for the 3853/3854 bulbs. Does anyone have any expected lifetimes (especially at 7.4 volts)?
