Hello All! I've been reading your forums for a while now and learning what i could from your collective wisdom. A friend and I are working on a project for his ultralight, we are attempting to replace the nav, location, strobe, landing, and taxi lights with leds. after some looking around and reading up Ive set my eyes on these CREEXRC LED Color:Green; Luminous Intensity:51.7lm; Viewing Angle:100°; Forward Current:500mA; Forward Voltage:3.7V RoHS Compliant: Yes CREEXRC LED Lamp; LED Color:Red; Luminous Intensity:39.8lm; Viewing Angle:90°; Forward Current:700mA; Forward Voltage:2.2V; Wavelength:620nm RoHS Compliant: Yes CREEXRC LED Color:White; Viewing Angle:90°; Forward Current:500mA; Forward Voltage:3.5V; Luminous Flux:51.7lm and for drivers: 3021-D-E-700mA, BuckPuck # Max Output Current: 700mA # Max Input Voltage: 32VDC # Min Input Voltage: 5VDC # Simple 7-pin SIP connection, through-hole PCB mounted # Optional externally mounted pot. intensity control (0-100%) # External analog/digital intensity control (TTL compat.) # Drive up to 18 1W LEDs & up to 6 3W LEDs # Output short circuit protection up to 15 seconds # Output open circuit protection # Small form factor .78"x.78"x.43", 8.1grams # Built in regulated 5V reference/output to power local logic circuitry/µProcessor my thinking is this, two teardrop shaped pods one for the tip of each wing. on each pod 3 color leds on the raised side, 3 white with a slow, 40 to 120 blinks per min, strobe across the top and on the back end three white steady. the steady white and the color can be on the same circuit, 6 led. i need to find a diagram for a controller circuit for the blinkers though. if i can get a diagram and maybe a parts list i can put it together. or if there is a led driver that will already do this id love to know. for the landing lights he needs to be able to throw a spot as far as possible. he needs to see the runway as soon as possible. at first i was thinking in terms of brighter is better but ive been looking at some of the flashlight mods on here at i thought it best to ask your advice before i spent money. for taxi lights, he just needs the equivalent of a single car headlight on low. the electrical system is a standard 12volt with an alternator. any feedback would be very much appreciated!
