Hello everyone!
My name is john.
I want some help with a project.
i bought this light "7500"lm 5 xm-l t6 etc etc off ebay.
http://www.ebay.com/itm/391029237067?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT
I want to install it on a little moped bike.
It has a 12v, 5ah, lead acid battery.
The light has a driver that *i think* has a max input voltage of around 8.4v.
the seller told me that it wont work below 7.4v but i have tested it with a battery pack made of 4x1.2v-AA bat wired in series and -albeit "just" 4.8v- it worked.
Then i hooked it up on my trimmer charger (ac 220v to dc? 3v @ 1000mA, 3VA) and it worked again.
so i suppose it doesn't matter at all even if the voltage is down to 3v.
I didnt notice any difference in brightness when using 4,8 vs 3 volts.
Do you guys think it has any diference?
maybe from 7-8v range?
The button led was solid red when 4.8v was used and blinking red when on 3v supply.
So the real question is...
i was thinking of buying a usb charger wich converts 12v to 5v and use it as a converter.
Is it a good idea or not?
also.
why?
will it be dimmer when on 5v rather than 8.4v?
if you guys think that it will be a good idea, what mA rating should i get.
is 1000mA enough?
please help me clear this out!
thanks in advance folks! :wave:
