HID Landing Light
Other than the absence of a suitable mount (easily fixed), does anyone see
any problem with this light as a landing light? http://www.trailtech.net/4211-SX-150.html I'm considering upgrading from a 50W Halogen lamp, and understand that I should get ~2x the lumens from a 30W HID. This light has a 12 degree beam angle and the housing is 2 3/4" in diameter. Their floodlight (in the same housing) has a 36 degree beam angle. Thoughts? KB |

KB I didn't see any specs for the motor cycle light you are looking at... I do know that the one these guys sell puts out way more light than a standard landing light and has longer life. http://www.knots2u.com/HID%20Light.htm The motorcylce HID you are looking at should have longer life than a Halogen as well, I just didn't see anything about how much light it generated...

There are many cars, and have been many for about the past 3 years, that are equipped with HID's, and would put out a lot more than this pint sized motorcycle head and handle bar lamp. Read "magnitudes" more. I would think that the selection and price would be pretty good, by now. Also, many have lenses that could be spaced at different lengths away from the light source, for an adjustable focal length. That sounds like a very good option, to me. -- Jim in NC |

You have made some good points. At $149, that is a deal, compared to the prices of the other HID units in their inventory. This must be an intro price, or something. -- Jim in NC |

One of the issues I've always *thought* existed with stuff pulled from an auto is that you may also need to use the headlight lens that came with the car, because the lights themselves only include a reflector, bulb, and ballast, but not an optic. I think a Lexus (tm) headlight lens assembly would look pretty unusual on my RV-6. ;-) That raises some interesting questions, and I admit that I have not looked at any to the automotive HID units with that in mind, or attempted to dissassemble them. In theory, however, some cutting would be required, since I believe that they are made to conform to the definition of sealed beam. As far as I know, the definition of a sealed beam lamp is that the external lens and the reflector are "manufactured" as a single unit--which can not be dissassembled and reassembled in the normal course of service. A carefull look at some of the halogen headlamp assemblies on some of the less expensive newer cars suggests that it would also be technically correct to glue/bond a plexiglass lens onto one of the older style sealed bean headlamp bulbs, as a secondary manufacturing prosess--thus creating a streamlined sealed beam headlamp. All of that is a, possibly long winded, way of suggesting that the HID headlamps on cars sold in the US might simply be a permanently glued version of more fully maintainable headlamp assemblies sold elsewhere. In other words, we may simply be giving up the ability to replace the plexiglass outer lens in order to comply with laws mandating sealed beam lamps. Therefore, the possibility exists that the outer plexiglass lens could be cut away from some of the HID headlamp assemblies, and that sufficient structure might remain to support all other portions of the assembly--including the primary focussing lens. A new plexiglass lens could then be a part of either the airframe on the lamp assembly--since there is no sealed beam requirement for an aircraft. Some of the HID headlamp equiped cars are getting old enough for the outer lenses to cloud over in the southern parts of the US, so some assemblies could be available from salvage yards at very reasonable cost--depending upon the cost and longevity of the light and balast. The beam width, however, will be *much* greater in the horizontal plane--which could be an advantage for taxiing. If anyone has occassion to try any of this, I am very curious as to the result.

A single lamp including ballast circuitry was about 250 Euro (~ $325) when we bought it last year Rob |

HID Landing Light
The HID headlights installed in cars are for the low-beam application.
These wide angle lights aren't very suitable for landing lights unless you install them in a different, narrow beam reflector. Off road HID lights work better as landing lights. I suppose your could rig up something suitable out of a set of off road light housings and the guts from a set of junkyard HID lamps. I admit that I've wondered about high and low beam. The ones I've seen on the road appear to cover both the high and low beam applications, but I have no idea how they do it. Peter |
