Converting a Lantern from bulb to LED
I have a number of bulb lanterns (6v - 4 D cells) that I would like to
convert from bulbs to LEDs. Is there a convenient LED conversion adapter available for this type of conversion? If not, what would you recommend for the suitable LEDs and driving circuitry. Presently the lanterns are able to be dimmed by an external dimming control which is a feature I would like to retain. Thanks for any suggestions you might have to offer. TMT |

Thanks for any suggestions you might have to offer. TMT I think you would find that a single 3-watt Luxeon would work most like what you're used to. It would compare favorably with the incandescant bulb performance. Check out Ever-LED at http://www.theledlight.com/ledbulbs.html If you are doing several and have some appetite for screwing around, you can do it for considerably less money in total. Circuit boards would cost somewhere between $5 and $7.50 each in lots of 10, 3 watt Luxeons are about $5 each, and the remaining parts would probably be under $10 per light. You'd have to do a little machining and futzing around. I don't have boards for sale, but I wouldn't mind designing, doing the layout and ordering some boards in exchange for a couple of boards. In a 6-volt light I'd use a synch buck regulator -- constant brightness throughout battery life. These can be dimmed with PWM that can be easily produced in a variety of ways for a couple of bux. Email me offline if you'd like to pursue this. I love playing with flashlights! An alternative is to just use a whole bunch of "high brightness" white LED's. It would take 40 or 50 of them to be comparable to a 3-watt Luxeon in brightness, and it won't have nearly as good a beam or "throw". |

TMT Hi T I have a 6 volt lantern that Don Foreman helped me convert to LED. It is sensational. It's spot is better columated than the original incondescent, and brighter. I can tell you what we did, but, if you can get Don's attention you can get the best information available. Jerry |

Converting a Lantern from bulb to LED
Ah! That's a 1-watt Luxeon. I think the OP might like a 3-watt
better in a 4-Dcell lantern. I would also go with a Lambertian highdome Luxeon rather than the sideshooter the EverLed uses. The sideshooters are fragile, and they don't produce as uniform a beam unless a faceted reflector is used. On Wed, 1 Feb 2006 12:11:21 -0600, "R.

Definitely worth considering for a 6-volt lantern. I don't have any price info yet. |

Don,
Thanx for the link to the lite site! It sheds cool new light on the subject. Bob Swinney "Don Foreman" wrote in message ...
