brightest 6d maglite bulb?

[jasonsmaglites]

i've got a 6 cell maglite i'm hooking up for a friend.
what are my best bulb options.
i have a bunch of 6cell magnum star xenon already.
i know about the 5cell bulb working in a 6cell light.
that might work for my friend, but is there anything brighter, or more reliable.
something designed for 6 cells but draws more amps.
like the rop low bulb, but maybe a touch less power so we don't melt the reflector.
thanks, jason

No need to let the reflector slow ya down.
Get a metal one and go for the ROP option. :rock:

i personally have two reflectors.
both medium stipple, nice flood lights.
however, my friend does not want $60 into a flashlight.
he just wants to pay $25 for the 6d light and maybe 5 bucks for extra bulbs and upgrades.
so i'm wondering do i hunt down some 5 cell xenon or something from radio shack or better yet something ALMOST as bright as the rop low but with long bulb life too!
i heard of radio shacks kpr112 and 118 but i forget which they go to.
SOMEONE GET ME A GOOD 6D MAGLITE UPGRADE CHEAP!!!

I know, I know!

You want a PR bulb that is slightly less than the RoP-low?

The bulb you want is the Philips HPR71 (made by Philips Germany)

Philips claims 210 lumens at a rated 6v, 10w.

Pelican claims 290 lumens at 6v, 11w for the 3854L.

The HPR71 is standard equipment in Australia's Rechargeable Dolphin.

I ran rop low with plastic mag reflector, few min. at a time, after couple recharges of the batt. still no melting noted.

Any idea where you can get this in Aus? Are they available online or even a store in Sydney?

Bunnings Warehouse.

Sold, as I said, as the globe for the "Dolphin Rechargeable".

You're in for a treat. Easily doubles the output of an overdriven KPR113.

Thanks lctorana
Didnt think it would be that simple!!

 

[gratewhitehuntr]

DX ( I think DX, maybe kaidomain.com though) sells an aluminum reflector for $10.
free shipping

Only in smooth though

 

[jasonsmaglites]

doesn't seem as efficent.
what do you think.
is there anything else?
can i get a link?

what about 7 C cells in a mag 6D overdriving mag 6D bulb?

Good idea, and worth a try, but the HPR71 with the existing 6D batteries would give more than double the brightness.

hmmm... is it just me or wouldn't i rather have the extra one watt and the much higher lumens.
i just found out dx sells a $10 reflector that can handle the heat.
does that make our old fivemega reflectors obsolete?

 

[lctorana]

Jason,

My recommendation was a response to your original request for a bulb "like the rop low bulb, but maybe a touch less power" in post #1.

The HPR71 is exactly that - like the RoP low, but a touch less power.
I answered the exact question you posed.

If you want to change reflector and lens, then RoP low or even RoP high can be used.

 

[jasonsmaglites]

i do appreciate your post.
i especially appreciate the link someone gave me to the $9.99 reflector that can handle the heat.

what i was trying to say, is it would be awesome to have something more like 5-8 watts, that had the same lumens per watt as the rop low.

the bulb you mentioned SEEMS to be less lumens per watt.
so i'm pulling the same power but getting less lumens.
the reasons i was looking for less than 11 watt bulb was not for less brightness, but
1. longer runtimes
2. capable to use with alkalines
3. won't melt stock reflector

that bulb didn't really meet those needs, BUT it was because i wasn't making myself clear.
i may just upgrade him to that $10 reflector and keep the rop low.
what do you guys think?

by the way, how much are those bulbs you were referring to vs the rop low bulbs?

 

[jasonsmaglites]

does anyone know how to stipple our mag reflectors while giving them heat protection at the same time?

like stippling with heat resistant paint?

 

[lctorana]

Jason,

One thingyou must understand about incandescent bulbs is that, all other things being equal, efficiency improves with higher wattage.

The classic example is: which is brighter? Eight 25w bulbs, or one single 200w bulb? Answer - the single 200w bulb - by far.

As you go down in power, the lumens per watt decreases.

Yes, Philips DO make a 6v 6w bulb (the HPR73, 110 lumens) is in the catalogue, but the lumens/watt is even lower.

That said, IMHO the HPR71 to the naked eye is a match for the RoP low bulb - it physically resembles the RoP-high bulb, and matches some reflectors better.

And - at 10w, it is as high as you can go with the plastic reflector. Remember, when you overdrive it to 7.2v, you are pumping out over 300 lumens, which is enough to put even a Malkoff down. It is the ultimate bulb-swap-only mod you can do.

Take it or leave it.

We are talking about a 6D configuration with alkalines aren't we? Will the Dolphin HPR71 bulb handle 9V.

 

[lctorana]

Lol!
Show me alkalines that will deliver 1.5v into a 2A load, and I will be the first to buy them!

But Jason has moved on since the start of this thread. Since Kai sell aluminium reflectors and 52mm glass lenses cheaply, he now has the freedom to put in the RoP low or even the RoP high at a reasonable cost.

The HPR71 discussion is really only academic now.
