It looks like the SB1B-14 is designed for only the BC410-H Alternator. The LR3C is designed for many generic alternators. Contact B&C to be sure before ordering. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=452223#452223 ________________________________ Message 2 _____________________________________ Time: 10:18:02 AM PST US Subject: AeroElectric-List: Landing lights From: John Tipton Hi Guys Does anyone see a problem (electrical interference etc) with fitting these LED (landing) lights, into a Duckworks RV9a wing leading edge http://www.ebay.co.uk/itm/141622765613?_trksid=p2055119.m1438.l2648&ssPageName=STRK%3AMEBIDX%3AIT Best regards John Sent from my iPad ----x--O--x---- ________________________________ Message 3 _____________________________________ Time: 01:24:27 PM PST US Subject: Re: AeroElectric-List: Landing lights From: Rob Turk It is rated 10 - 30V so it has at least some kind of switching constant current circuit built-in. That may cause interference, but it is encased in a metal housing and some suppression stuff (ferrite beads, LC filters) go a long way in minimizing this. Keep the power cables away from your COM antenna though.

There is a very large range on the quality of reflectors, emitters and drivers out there. Just like most things in Aviation, your best bet is to go with something that is known for its quality. Stick with something that uses Cree Emitters. Cree LEDs are the best and brightest in the business and will last a long time. The driver is what will make the noise. Not the emitter itself. There are some write ups on the VAF forums that discuss the Baja Designs LEDs. He put them in the wingtip of his RV and took good pictures of the project. Take a look at them. They use the Cree XLM emitters and are very bright and drivers create no noise. http://www.vansairforce.com/community/showthread.php?t=105248 Some guys are also using the "trustfire" flashlights. They also use the Cree LEDs but the flashlight driver makes them very loud and noisy. There are some trustfire write ups on VAF forums as well. Hope this helps!

Are they holding up well in service? How difficult is the installation on a Yak 55? Thank you!

The LR series regulators are designed to drive legacy alternators in either 14 or 28v systems. They feature internal ov protection and lv warning. The SB1 series regulators also feature ov protection but their lv warning systems are replaced by a circuit that monitors alternator output activity which is normally zero when the main alternator is running. Should the main alternator quit, bus voltage falls, the standby alternator wakes up and a panel mounted "ALTERNATOR LOADED" lamp illuminates to announce the change in system status. Further, an output current sensor on the b-lead will cause the ALT LOADED light to flash if there's too many demands on the SB alternator's capability. The pilot shuts things off until the light stops flashing.
