  • Approximate LED OPerating Point

    posted by apoapsis

    Experimentally determined operating point of LED at about 7 ma and 6 volts. Light ouput bright and reverse current in single digit uA range.
    The high data point at about 9 volts and 200 ma was only held less than a second!! Talk about bright ;-)
    Not hard to figure out approximate curve, but I need to get a 4 - D cell holder to verify the 6 volt current.
  • Very nice light

    Very solidly build. Has a nice feel to it! Nice strong light beam produced. Has a great power factor when compared to other LED lights I have tested (this one is arond 90% PF which is excellent) In my testing it didn't get excessively hot.
    While I am awaiting a replacement I haven't been able to study it's internal design. However with a strong light output and great power factor I believe it's designed well internally. If I could find a use for these then I would definately buy more.
  • Bright bulb, nice light for eyes

    Good big lamp, that shines brightly and gives much light to your room. Has plastic casing and it protects led's form dust or damages. Light is soft, not blue cold an can be used in living rooms.
    No thoughts - it serves as lamp and gives light, so what else?
    Good lamp, good color, much light, worth to buy
