DX sku.14150

ooo, nice find dhouseng = http://www.dealextreme.com/details.dx/sku.14150

Just bought one 5 mins ago

actually for both...since i'm moving to a new house soon, so might need to get something 'handy' since i'm staying alone in usj. haha......

the battery that u mentioned, it is kind of hard to find and not cheap. the problem with thos d cell battery is that although i remove it from the flashlight in my car, it still discharge by itself.

i forgot to mentioned that i dont mind about led or those normal bulb, as long as it can focus far, bright and sturdy, it is fine. LED is not cheap, so within my budget...led should be out of the question.

i had check the website, it seems that the review is not that good. i guess maglite 4cell c should be ok....haha....i just like those US/HK police flashlight...long and sturdy.....thanks a lot for all the input......

Hi Yothim,

With LED out of the question, and staying with your requirements and quality expectations, perhaps it's better to get the Maglite then. I don't think you can find a spanking brand new 4C Maglite below RM100 here. Spend that little extra for the original and you'll never regret it. Buy spare bulbs too, they last forever.

My bro-in-law has a 4C Maglite which he owned for close to 10 years now (a very good investment). Keeping it storage overtime the alkaline batteries corroded and it has to go through some major cleaning to have it work again. Just watch out when using alkalines and not to leave them unattended in the light very long. I gave him an Eagletac P100C2, an LED light (that runs on two CR123) which was a perfect car light and defense tool. He's still on the first two CR123 battery for a year now. The 4C maglite is home guarding the house.

CR123 batteries are getting more popular these days and they are within reach in our country. We have dealers who stock them enough for a disaster event and you can find them in Tesco and camera shops as well. We recommend CR123 batteries because you can keep them for years without worrying that it will corrode and leak in your expensive flashlight. Most general users only use it momentarily and when a blackout occurs, and tend to store alkalines in flashlight for years without realising it leaked until they need it.

Let us know once you obtained your Maglite

Hi there. I am William, the designer of the PhD-M6 custom pack. I noticed the references to my PhD-M6 pack so I decided to stop by and answer/clarify some of the questions I saw.

The PWM is not bad for the bulb's filaments, in fact, it has been used successfully for decades. The soft-start and the regulation greatly extend the life of bulbs, so the benefits are real and tangible. Willie Hunt was one of the early pioneers in using a micro-controller to create the PWM signal to regulate incandescent bulbs, and his old web site still has a lot of very good information and explanations as to how PWM works:
Lightbulb Voltage Regulators



That is correct. Although I don't know first hand exactly that algorithm/frequency AW uses in his soft-start, multi-level driver, his driver and the the PhD drivers (including the PhD-M6) use PWM to provide the soft-start. What the PhD drivers adds in addition to the soft-start is the voltage regulation: as the battery drains, the duty cycle of the PWM signal is adjusted to maintain a constant voltage at the bulb, to achieve a constant brightness.


If I can be of further help to clarify/expand on anything else related to the PhD-M6 pack, please do let me know.

Will



The PhD drivers use a frequency of approximately 250 Hz. This is fast enough that to the bulb, there is no ON/OFF cycles, but a constant level as the bulb's filament is averaging the PWM signal to give a constant RMS voltage.

Hey William, thanks for the clarification , learn a lot from you today, you are so generous to share your knowledge here, thanks again.

I had also just realized surefire A2 incans are regulated, not sure it is PWM or current, but it does (reported by users), prolong the bulb's light up to 100%.

WOW
wquiles the master Mag builder from CPF is here

Will, the greatest Mag 1D modder is here. Love your work.

The PhD-M6 is a great engineering stuff but the price is too high for me.

Welcome to the forum.

The A2 is a very unique light, in that it was designed (at least the electronics) by Willie Hunt. The A2 (like the PhD drivers) has both soft-start AND regulation via PWM.


Thank you


Thank you


I understand and I can certainly respect that.

Although the price of the components is not that high, the $1-2K in development/tools/software costs, many months of development, testing, 2 prototypes, and the final hand soldering/assembly/testing/calibration labor just adds up to make it a bit expensive.

Alan B and Jimmy also make PhD drivers for the Mag platform, and their solutions tend to be less expensive, so you guys can always consider those if wanting the soft-start, regulation, and low battery warning.

Some maglites for fun.





Have a nice weekend.

jwyj and of them made by wquiles?

Anyone knows where to get the powerful Maglite torchlight? It is for self-defense purpose. Last time can be found at ACE Hardware, now no more already. Is it kena banned?

'Powerful' is subjective, if you want ones that are as powerful as the ones in jwyj's collection above, you'll have to buy a standard Maglite and modify it yourself. Or buy one from jwyj...

Anyway, Maglites are definitely not banned. You can still find them sold in Ace Hardware - I saw it in Jaya 33 yesterday, the other Ace Hardware stores should have them as well, maybe the one you looked in decided to use shelf space for other things.

WOW James...that's an awesome collection of Mags. That purple Mag, what's in the head?

All of them are made by CPF member VestureOfblood.

From left to right.

Osram 6 die emitter powered 3 black AW C cells and blue shark
SST-90 powered by 2x IMR 18560s with 10A buck
SST-50 powered by 2x18650s H6CC driver
4x NW XREs powered by 2x 32500 D cell li-ion 3 mode driver 1.4A per die.
10 XPG R5 powered by 2 IMR 26500s DD runs about 1.5-2A per die
5x XRE R2 powered by 2x 18650s 3 mode driver.
4x XPG R5 powered by 2x IMR 18650s DD 1.4-2A per die
3x NW MCE powered by 2x IMR 18650s DD 700ma per die.

I am also thinking of letting go a few.

really lots of current drawn!!

Imedion 2400mAh AA


http://shashinki.com/shop/maha-powerex-ime...facturers_id=13

That looks like a great deal. Any side-by-side comparisons with Sanyo Eneloops?

The "Maha PowerEx MH-C9000 WizardOne Battery Charger & Analyzer (New Improved Version) + Imedion 2400mAh Batteries (4pcs)" package for RM315.00 looks like an ever better deal for those who are considering getting a "serious" charger

Oops... think first.
