Microscope halogen light power supply? volt 20 watt bulb and amps?

Hi, I joined this forum last year and found it to be very welcoming and helpful when researching bike lights for mountain biking. I wound up buying the Shadow BL21 lights from intl-outdoor dot com and they are amazing for the money. The mount to the bars is better if you buy the upgrade mount for about $4 other than that the batteries last for over 2 hours not sure how much longer but no signs of fading at the 2 hour mark :] Customer service was over and above!!

Thanks for the help with that I`m very happy with the outcome and used them 2 and sometimes 3 nights a week for about 3 months with no worries. Just needed to separate the male connector prong that has a split down the middle so it was a wider gap and all was golden…

Sorry this is not a flashlight question but I`m not sure were else to turn for help and advise.

I`m now trying to work out how to power the 6volt 20 watt halogen bulb that is in my microscope.

The thing is I want to move the 2 heavy duty transformers that are powering the light far away from the microscope due to the high Magnetic field they are giving off that I measured to be over 2000 milligauss :/ I used my Alpha Lab AC Milligauss meter Model UHS2.

So without having to remove transformers & all the wiring I just wanted to detach the wiring from the transformer & be able to plug in a power adapter direct to the light that will run a 6 volt 20 watt bulb so 3.33 amps???

Any Ideas how I should go about this? I do not know how many amps I really need to run the bulb?

when I used my multimeter it was reading a steady 3.5 to 3.7 volts and when I lightly touched the wiring I could get a quick temporary read of 5 volts then it would go back to the 3.5 to 3.7 volts so I`m a little confused if I need the full 3.33 amps?

It would be great if I could an adapter and use a batteries as another source for power just not sure if batteries that would power that bulb?

Thank you in advance for your time and help, Have a great day :]

you should be able to make up a C or D cell 6V pack that will power that bulb just fine and they’ll be able to handle the initial current spike well too. Run time will be in the couple of hours range, I’d guess.

Personally, I’d screw a 4500K tint XM-L to a chunk of metal and power it off a simple linear driver and 5V USB wall wart. Less heat and no more replacing bulbs. I don’t know what ones you use, but some of ours are only rated for 40h, which is flat out ridiculous. I’d love to replace them with LEDs, but I don’t think my boss would appreciate me messing with a $60K microscope Smile

What are you using the scope for, BTW? I’m really curious about the sensitivity to magnetic fields..

Hey Mat, thanks for the reply. I want to stick with the Halogen light since it is as close to natural light as I can get without using mirrors, the LEDS with prolonged use can and will affect your mood if you want more info about lighting and your health checkout this guy http://www.youtube.com/user/StevenMageeBooks?feature=watch
He has many books, I bought his book toxic electricity and recommend it to everyone who will listen seriously for the $15 you spend you get and life time of EMF awareness, if you are even slightly interested about sensitivities to EMF get it.
I spent a couple months pretty much solid in my spare time researching EMF online from YouTube videos and documentaries to Google research, reputable books about healing and thought I learned most of what was out there. I was wrong :/ Toxic Electricity by Steven Magee is packed…

I removed the CFL or curly bulbs from my home about 2 months ago and the next day I had no cravings for sugar like I have had ever since I started using them, crazy for years I thought maybe I was becoming a Diabetic I always had the munchies and I`m a fit guy who eat`s healthy it turns out the CFL & LED bulbs that run on AC affect your sugar metabolism and I`m living proof of that. So no AC LED or Florescent bulbs near my microscope for sure :/ I`m not 100% sure about the DC side of it but I do know that when you use the dimmer function the electric field & Magnetic filed gives of harmonics so best not to use the dimmer if it`s close to your body….

Here is a video I did about my Microscope and the emf, My voice is suppressed due to allergies so hope it`s clear enough.

I have a couple other video’s about EMF awareness just check out my channel.

I bought the Microscope for fun & to view my own Blood. Live blood / Dry blood analysis and self diagnose my allergies as Doctors will only suggest drugs…

I`m learning a lot about proper nutrition & realized my allergies are being caused by Candida, I`m not 100% sure if the blood analysis shows the yeast build up in the blood as there is some controversy in this area but my symptoms, diet match the Candida.
This past week eating Raw food only with the exception of Chicken, red meat & hard boiled eggs for my protein source and have noticed my breathing is wide open, this is a promising sign…

Mat if you want to PM me and discuss EMF or Blood analysis go for it, maybe you can give me some pointers using my $300 microscope?
