for the mica heat shield...follow this link..: https://www.candlepowerforums.com/threads/48848
The 5761 is quite floody.. Despite a slightly yellowish beam on a mc battery stick, it remains one of my favorites :candle:
might be a little offtopic but concrning the magcharger's reflector...is it all metal? and how much heat can it take without any damage?Is it worth upgrading to another smooth reflector(custom?) if someone wants max throw? Thanks!
Philips 5761 won't fit in stock reflector unless bulb opening is enlarged.
For extremely hot bulbs ceramic slug is best choice.
It is not a good idea to mix NiCad with NiMH for a pack.
All batteries must be same chemistry, same capacity, same age and healthy.
MC stock charger is constant current at 220mA and can recharge 6 series NiCad or NiMH batteries. So you will need to charge batteries according to your batterypack capacity.
Example:
If your battery pack has capacity of 4400mA and efficiency is 50%
(4400:220)+50%=30 hours.
So regardless of battery numbers in a pack*, a depleted 4400mAh battery pack needs 30 hours charging.
* Remember, stock charger can charge battery pack of 4, 5 or 6 cells at 220mA
Advantage of AA cells are that you can use LSD Eneloops while LSD is not available in 1/2D size. Also 6xAA needs a "D" dummy without extending flashlight length.
I do.
Only the reflector is metal but reflector base is plastic.
Is there such a thing existed?
Depends on bulb/battery set up and how long you want to use it continuously.
MC ThrowMaster is the answer.

Hi, I know this is an old thread, but I stumbled across it while searching.
Long and short of it, based on reading in anther thread that a Phillips 5761 bulb was a no mod drop in for my MagCharger I went online and order one. Or at least what I believe to be one.
Anyhow, when it arrived it was obvious it was physically bigger and wouldn't fit through the reflector properly. I did however plug it in and try the lamp briefly with the the reflector and lens removed. This has lead to a couple of questions:
1. It wasn't very bright, not at all, sort of an orange glow. Do these need time to 'warm up' or should it be instant? I turned it off after about 5-8 seconds. I'm fairly sure it's the right bulb as the packaging says Phillips 5761 6v 30w.
The standard MagCharger bulb works fine when I tried the same thing (lens/reflector removed) and was as bright as normal.
As far as I know the MagCharger is working fine, the standard bulb is as bright as it was when new. It's the earlier NiCd version. I also tested the battery pack in a 3D Mag with a standard incan bulb in, this made a huge difference in brightness/whiteness compared to a new set of Duracells it had in it. So I'm assuming the NiCd pack is still pumping out all of its 6 volts.
If anyone could point me in the right direction to solve this I'd be most grateful.
2. Assuming I can get it working, what is the easiest/best way to enlarge the hole in the reflector without causing damage to it?
3. Reading this thread it seems I also need to consider a heat shield, does anyone know where I could buy it in the UK?
Thanks.

Original MC bulb consumes only 1.8 Amps while 5 Amps draw of 5761, may sag your unhealthy battery pack to lower than acceptable voltage.
I recommend recharge it before retry and if result is same, you may need new battery pack.
You can also check current draw at tail cap which must be about 5 Amps.

The fact that the 5 cell ni-cad stick didn't flash the 3 cell bulb makes me suspicious of its health as well.
Additionally, my 23 watt Welch Allyn 1160 bulb doesn't look all that much brighter than the stock MC bulb when you view it without the reflector. Only after screwing everything back together do you see the real difference.
CPF member Northern Lights is the fellow who first started using the 5761 in a MagCharger; I'm sure he would be glad to respond to a PM about the best way to go about enlarging the reflector hole.
I'm not sure that the mica shield is as much of a concern with the 5761 as with some other bulbs due to the fact that the bulb's glass base doesn't recess into the plastic MC slug as far as the others do. CPF member Andreas Ferrari says he never has used a shield with his MC and the 5761.
You've already gone directly to the extreme end of MC hotwires with your purchase of the 5761; it's pretty much a given that you should upgrade to the NiMH battery stick as well. It's going to make a huge difference in how white that bulb stays, and for how long.
As Fivemega said: the first order of business is to see if your stick is even putting out anything close to 5 amps.

Thanks for the replies. What do I need and how do I check the current draw at the tail cap? Seems I've got a lot to learn

I just remembered that fivemega offers aluminum MC reflectors with a larger hole made to accomodate the 5761. It's a nice option if you don't want to ruin your existing reflector by enlarging it only to later find that you'd rather use a smaller bulb. You want the 11mm one. Its hole is large enough for the 5761, it's made to compensate for the added filament height of the 5761, and also has a textured surface which will make the beam look a lot more "Surefire-like" in quality.

Does anyone know if the phillips 5761 bulb will work with the new 2 stage magcharger?
Does the electronic switch limit any current in any way?

Did you do anything with your MagCharger yet? There are several (3) upgrades available only for the MagCharger, they run around $60-$90.
(1) The "TerraLux MiniStar30MR-EX" that puts out 600 lumens.
(2) The lower output is the "TerraLUX TLE-300MR EX-S" that outputs 700 lumens.
(3) And then there's the "TerraLUX MiniStar31 MR-EX" that outputs 1000 lumens.
Make sure you put in a thermally resistant lens to go along with the high heat output bulb...

I bought the fivemega kit several months ago. I am running this setup in the standard single stage magcharger. It would be nice to have the lower mode for longer runs using this kit, but my cheap DMM is showing a 5.7 amp draw. I am just curious whether or not the new switch can handle the current.
Has anyone taken apart the new style switch yet?
