  • Long-running tuned MC-E flashlight

    posted by prcoder

    - Finetuned for long runtime
    - Spring is soldered to switch
    - Good switch to tailcup body contact
    - Serial connected MC-E dies
    Flashlight uses boost conversion circut controlled by PIC-alike microcontroller.
    PWM-controller DIM pin and feedback pin controlled by MCU.
    All MC-E dies connected serially and powered near 12 V from boost convertor.
    I made some measurements while powering flashlight from 8.0 V lab supply:
    HI mode 350 mA on LED (4.2W OUT), 650 mA from supply (5.2W IN) EFFICIENCY=81%
    LO mode 70 mA on LED (0.84W OUT)), 120 mA from supply (0.96W IN) EFFICIENCY=88%
    Strobe current slowly varies 200..350 mA from power supply.
    LED module is massive and made from brass or bronze.
    Good, but not perfect thower based on parallel-connected Cree MC-E LED. Probably can run about 3 hours 45 minutes at HI and more than 20 hours at LOW mode. Optimal brightness/runtime currents choosed.

    great product.... lots of fun in the bathtub.... just screw it in and it works.... colors are very beautiful and change with ease.... it is safe for little kids and shows them how hot the water is.... keeps them safe...
    the handle does not get too hot to hold .....maybe some rubber or silicone on the handle will make the product even better.....
    if your kids want to have fun in the bathtub this is the product for you ......just be careful of the water bill.......
  • Fancy lights

    Real fun for low budget. Light shine very bright. Easy to mount. Everybody is looking back to see what is running on the street.Included baterries last for really long time.
    I recommend this lights. Really fun to use it. And the most important thing, you are more visible to other traffic users.
    Great deal.
  • could have been a lot brighter

    good build quality, feels solid in the hand. the beam pattern is nice with a good spot with a nice even spill. looks like a cree XPG emitter
    an okay light for the money, lower power just means it will run a lot longer, down side if your after a supper bright light look else where
  • Works fine

    Nicely built, works finelot of light, ease to install
    the color temp doesnt match my expectation... has strong green component...the light is a bit greenish! not very comfortable as incandescent light bulbs... impossible to use in kitchen or bathroom.. although you and your food will appear not health at all!
    nice, but not for me!I am buying another one with better color quality the light is a bit greenish! not very comfortable as incandescent light bulbs... impossible to use in kitchen or bathroom.. although you and your food will appear not health at all!
