New G4 pin 35w 6v overdriven to 14.2v >8,000 lumens
« on: November 14, 2007, 12:12:00 AM »
New bulb came in today in cooperation with AW and Northern Lights. Hooked up to kiu socket to bench power, Only marking on bulb 6v, 30w.

6v=2.5A
7.13v=3A
8.03v=3.5A
10.7v=4A
12.25v=5A held 14.2vbulb for sometime. at next increase,
14.6v=POOF

The main reason for this somewhat early released hotwire is cost. $3.50 per bulb is alot less than what have paid for some other recent released mods.

14.2v at the pins in kiu socket powered at the bench, measured by Fluke DMM vbulb are all the measurements listed below.

It is a G4 bi-pin halogen with 8.86mm diameter, reasonable priced can afford to work it up and play around.

I got 5A reading from my analog, someone else measured 7A. My analog moto AC, CC bench supply may be out of calibration but measuring the vbulb with Fluke DMM should be fairly accurate. So, the bulb is still in the workup stage.

Considering the recent advances in thermal management, running 9A bulbs in bipin adaptors utilizing said management techs, pedistals are not melting so I'm not planning on using anything else.

Mag switches will be as effective as modded. To run 9A with moded stock switch reducing resistance and at the same time reducing amount of heat produced not only increases vbulb but doesn't melt down the plastic switch.

I like batteries that don't sag much and have flat discharge curves so have switched over most of my mods to run on A123's or Emolis. Because of the flat discharge curve only need a $1 NTC to bring down overhead voltage to meet bulbs specs. Such as 5761 with 2x emoli + NTC 8.2-3vbat and 6.9vbulb.

4x Emoli = 16.8vbat fresh charge, 14.8v nominal will work with NTC and post the results. 4 Emoli fit in 5C M@g form which I like. 4xA123=14.4vbat fresh charge, 13.2v nominal again will fit in 5C.

So if you want run time, emoli or A123 will give you I think the smallest form factor. 4x emoli fit 5C mod with 26700mah and say 7A is 7000/26700x60=22.8min run. What size would be needed for Ni Mh of same run time? At least 3D, tri maybe quad bore, which is same length as 4C.

Where to get them? Ask AW for the chinese mystery bulb as it has become affectionately know.

happy modding jim

Hey Jim. Do you have any idea what this bulb is and what the voltage requirements could be?

I have never seen one. So, that's one on me. I'll bite what is it?

I'm asking you. It looks like a giant halogen bulb. I hooked it up to zip cord and plugged it into the wall and the zip cord burned up like the world's shortest fuse. The bottom of the bulb is frosted with some white stuff that feels like it was sprayed on. The other white stuff around the pins are from the smoke from the zip cord.

Yeah, one big halogen.  Send it to me and will hook up to bench supply with I'm thinking 25ft long welding cables and tell you the flash point.

Are you buckin' for an instant sunburn?  :D  what do you mean by flashpoint? You mean "poof"? This could be an expensive bulb for all I know so I don't want to find out. I may hook it up to my car battery (or two) though but I will be shielded with a trash can lid or something.  Maybe I'll make a huge flashlight with it or giant off road light - called "Cyclops"

That thing is evil looking knot!  Wonder if it's to something like a searchlight?  The filament orientation is probably a clue.

Sunblock won't help, the EPA probable lock you up for destorying the ozone layer.

Not an exact match, by any means, but it sort of looks like a military searchlight bulb:

E63 Thorn 220V CP41 2000W

Click on the picture for a better look.


I suspect your bulb is of a newer vintage, but that's just a guess. Looks like it may be missing the proper base.

Sorry about hijacking your thread JJ.

It looks, to me, that the bulb attaches to some kind of slotted receptacle/socket. Here is the blade with two bumps in the glass - I'm speculating, to lock the bulb in the socket
