jetjr Posted April 12, 2010 Share Posted April 12, 2010 Will a single 35W HID light, or rather the ballast cause VHF radio interferance, or any other problem? Im looking at using an automotive type one in a Jabiru due to low current requirement Any experience? Link to comment Share on other sites More sharing options...
jetboy Posted April 13, 2010 Share Posted April 13, 2010 I've got a couple different of 35W HID systems and they both are auckward (bulky) and put out RFI sufficient to be a concern and I have not found a suitable reflector to give the sort of beam desired. They make good jet engine ignition units though. What I use is a Halogen display lamp, the latest generation of these are near the same efficiency as HID and only available up to 45 watt (replaces regular 75 W halogen) The one specifically I use is Philips Masterline ES 12V 45W 08 deg I had a hangar shootout against a 4509 landing light (100W), a 50W halogen version of the same, a 60 deg Masterline and the 8 deg Masterline which was the best to use. These ones also have a curved front face and the burner assembly is enclosed, making them more suitable for the job Ralph Link to comment Share on other sites More sharing options...
jetjr Posted April 13, 2010 Author Share Posted April 13, 2010 Yeah, I had a look at a "compact" HID from Narva - not only big but heavy too. How do you mount these Gu5.3 lights? Jabiru have a housing which clamps to LH strut which may suit. Anyone know? Link to comment Share on other sites More sharing options...
Bill Hamilton Posted April 14, 2010 Share Posted April 14, 2010 Folks, There is quite a range of STC's HID light conversions for certified aircraft, the shielding is vital. Their specs. would be a good place to start. An important point not so far mentioned is they run cool, so lights on without a cooling airflow/ground operations is not nearly as critical as most other bulbs.
