So I just picked up a 6 D cell maglite thanks to ATHD for $16 and change shipped.

I know some of you frequent the flashlight boards more than I. I've been googling, but comming up empty handed. :(

I guess at the worst, I could use one of the 4 Cell bulbs(6.0v), use rechargable batteries (1.2v each), and use a dummy spacer cell.(1.2x5=6v).

hm.

Edit: Hmm, found some Luxeon solutions, but they're in Europe... and spendy.Well, that sucks...

We're sorry, we were unable to complete your order listed below. Unfortunately, HSN did not receive enough of this product to fulfill your order. The order has been cancelled.

I'm wondering why if the LED replacement bulbs I've seen work on the 2 or 3 cell Maglite's, why they wouldn't work on the 6 cell one.

Edit:

I need to find a LED replacement for the Maglite myself...but a normal 3 cell one. Hey...get in on that hot deal Eli? :p

;)

I noticed that and was confused as well.. Maybe the bulb is specced all the way to 9.0v or something.

But basically, LEDs require specific voltages and currents.. If you go over spec, they aren't very forgiving.. So there is usually some simple electronics in the circuit with the LED.

Since the components in the circuit need to change depending on the input voltage, this necessitates a need for different models. ;)

Since cells in a flashlight are in series, as you add cells.. voltage goes up.

1 cell = 1.5v
2 cells = 3.0v
4 cells = 6.0v
6 cells = 9.0v

A 1 Watt Luxeon Star LED requires 3.42v @ 350mA(max).

That means, with a supply voltage of 9.0v, I would need a 16 Ohm resistor in the circuit with the LED.

With a 4 cell flashlight, you would only need an ~8 Ohm resistor.

Well, browsing the good ole 'Net some more, it does indeed appear that the different numbered cell flashlights DO take different bulbs.

I wonder if we both saw the same page... I think it was a page selling knockoff bulbs or something, I don't know.

2 cell = Manufacturer Item #: LWSA201
3 cell = Manufacturer Item #: LWSA301
4 cell = Manufacturer Item #: LWSA401
5 cell = Manufacturer Item #: LWSA501
6 cell = Manufacturer Item #: LWSA601


2 cell bulb = 18 lumens
3 cell = 39 lumens
4 cell = 59 lumens
5 cell = 83 lumens
6 cell = 106 lumens

2 weeks on 24/7 is pretty damn sweet too! :Q

Bastard..

Finding cheap solutions to the 6D maglite seems to be a challenge.

The 5W would be nice, but it's 75 bucks.

Watch out for those Diamond 5W LEDs with the Fraen lenses. Some people on candlepowerforums have reported problems.

Yeah, the first problem being they are $75... ;)

Noted. What kind of problems?

I'm not really interested in one tho, too much money.

Arrr... Watch it, your ass may have a close encounter with Mr. 6D Maglite.

Well, depending on what you get..they are brighter. All of them are more efficient than the standard bulbs by a lrge margin. For instance, the replacement I listed above puts out 75 lumens, while the stock bulb puts out 39 lumens. Also, they battery life is extended quite a bit because the LED's use so much less power. I mean, with that replacement bulb and a 3D Maglite, I could keep it on 24/7 for two weeks....try that with a stock bulb.

Actually, that would be the last problem, the first problem being that you're using a MagLite. :)

Efficiencies are about equal for good quality, handheld flashlight bulbs and LEDs, but this comparison is not exactly apples-to-apples, as the incandescents in this class are typically brighter and have less runtime. LEDs are whiter, shock-proof, have less color shift on lower battery voltage (cf dim, yellow incandescents), and typically have driver circuits that extend usable battery life (by draining the battery further).

I have no experience with the drop-in replacements. A full mod will be more reliable and customizeable, and probably competitively priced.

With 6 batteries, you're going to see a wide range of Vbatt as they discharge, so I would avoid a simple resistor circuit. The cheapest reasonable solution is LuxIII + DownBoy buck convertor. A low Vf LuxV and an nFlex or uFlex board would be nice options. However, all this is $$.

Come on now, they aren't that bad. I got a deal on it, and they are decent flashlights for general use. Not everyone wants to build a custom flashlight, nor needs the best of the best.

Are you kidding? An LED is eleventy billion times more efficient than an incandescent bulb, all else being equal.....

I guess it depends on your specific definition of "efficiency" tho.

They use less energy, (can) put out more light, last longer.. the only real downside is cost.

I agree. Where is this 2 weeks x 24/7 (336hr total) coming from? I see "2 0" hours listed on the linked page.

The 75 lumens is slightly exaggerated, that's on the high side of a LuxIII T-bin and measured at the emitter (not accounting for losses at the reflector or lens). On the other hand, the 39 lumens for stock sounds like a pretty large exaggeration, though I don't have too much experience with large Mags. The Surefire E2e puts out 60 lumens, IIRC, which is "wow that's bright" to most people.

If this thread stays alive, I'll dig up some runtimes. Maglite stock bulbs are terrible, but good incandescents have strengths and weaknesses versus high-flux LEDs, some of which I mentioned above. I personally prefer LED, but it's not better at everything, and certainly not more efficient by orders of magnitude.
