difference in led bulbs...

This weekend I found out the difference between a $6.00 194 LED bulb, and $0.60 194 LED bulb.

I think the one for $6 is overpriced, but not too badly...

(picture coming soon)

I bought some led replacement bulbs for the clearance lights on my trailer from superbrightleds.com ... the little guys were $5.99 each, red and amber.

I liked how they worked, but being a cheapskate, I didn't like the price. So I bought some off ebay, from a USA seller. The ebay bulbs arrived quickly, and look nice, even with a color coded base.

But, plugging them in, they are VERY DIM compared to the ones from superbright, even though both use the same size LEDs... the "amber" ebay bulbs are also yellow, and not DOT amber, and the red are just pure red, not DOT red (which is more of an orangish)

The ebay leds are also bigger than the standard bulb, so the low-profile clearance light lens doesn't fit back onto the housing.

The ebay leds are going in junk drawer in my shop, and I'll be ordering a few more bulbs from superbright.

As a side note, there was nothing wrong with the incandescent bulbs that KZ put in my clearance lights, except they're incandescent... the bulbs were already starting to get soot build up, so they must have been poorly manufactured and regular air was trapped inside, instead of the argon/krypton mix that protects the tungsten filament.

    Make sure any you buy are not just 12 volts. Anything made for an RV should have a working voltage range of a minimum 10 to 24 volts.

    Be very careful here.
    Those LED "bulbs" have built in voltage regulators and most of them generate enough RFI to wipe out your TV and AM radio reception.
    Actually you have it backwards. The cheap LEDs DON'T have regulators.
    This is either a good thing or a bad thing depending on your usage. A few people have reported early failures of the LEDs from too high a voltage when on shore, or generator power. Many others say no problem.
    My thoughts are that he difference is likely how people use their TTs. Many boondockers use their generators during daylight hours to recharge the batteries.. Probably not using the lights then, so the lack of a regulator is no problem. Some are on FHU sites, and the LEDs could see a lot of time over 12 volts.
    And of course the non regulated leds won't interfere with the TV.

    I had already swapped to LEDs when I learned about this possible problem.
    So I hit upon the idea of installing voltage regulators on the two circuits that my LEDs are on.
    It was cheap at about $6 each and not too bad as far the install went.
    So I have the best of both worlds. LEDs that don't see more than 12 volts, and no TV reception problems.

    Exactly. I ordered several different bulbs until I found the ones I like. If their specs are correct, a 250-300 Lumins bulb should be a good replacement for an incandescent interior pancake light.

    I found the "Gold Stars" brand 280 Lumins LEDs on ebay worked very well and used them throughout my last camper with no failures. I just replaced all the lamps in my new camper with them. I can run 8 to 10 of them at once for about the same power draw as one incandescent. Big battery savings when boondocking and they don't generate heat.

    Have gotten burned by dim bulbs myself.. I will likely be placeing an order with Super Bright when I get back to Michigan.. For now I buy 'em one at a time and that's expensive.
  • As has been said many times. When ordering from China just get one at first to see if you like it. If you do, then order what you want.

    They are all made in China anyways, and oedering direct can be a huge savings.
  • Chinese manufacturers lie like a big dog. There is no way in hell to cheat an honest inquiry as to the current draw (that's AMPERAGE) draw per light. I've gotten answers: Honorable 7 watt light. .2 amps current draw. 100 watt extremely bright light, do not look at it, 1.6 amp draw.
  • I also replaced my clearance lights with leds from superbrightleds.com. They are working well. My incandescents were getting black and a couple had burnt out. The leds just keep going, and are consistent intensity.
