PeytonM Posted January 23, 2023 Report Share Posted January 23, 2023 I bought this as a standby 10 years ago, so like a fine wine, it has aged! LASAR says it’s $460, if they could get one! $130 shipping included. Note: I think the same light is used for both 14V and 28V systems. My airplane is 28V and incorporates a resistor Quote Link to comment Share on other sites More sharing options...
PeteMc Posted January 23, 2023 Report Share Posted January 23, 2023 If you get more requests after you sell your light, let me know. I'll be pulling out two 14v used/working lights as soon as the LED replacements come out. Quote Link to comment Share on other sites More sharing options...
PeytonM Posted January 23, 2023 Author Report Share Posted January 23, 2023 I think it’s the same light for both applications; the 28V systems include in step-down resistor. Quote Link to comment Share on other sites More sharing options...

PeteMc Posted January 23, 2023 Report Share Posted January 23, 2023 1 hour ago, PeytonM said: the 28V systems include in step-down resistor. Apparently some of the 28v systems did and others didn't. It was an issue when Whelen started designing the new LED replacements. Quote Link to comment Share on other sites More sharing options...
Pinecone Posted January 24, 2023 Report Share Posted January 24, 2023 I think it turns out that is was a misconception. Same incandescent lamp for both. But LED does require specific to 14/28V. Quote Link to comment Share on other sites More sharing options...
Marc_B Posted January 24, 2023 Report Share Posted January 24, 2023 From what I understand, the original WAT recognition light bulb was a 25W halogen that used 2 amps at 14V. So for 28V system, Mooney used a 7.5 ohm resistor that at 2 amps resulted in a 15 V step down in voltage; this allowed the use of the same bulb for both 14V and 28V systems. The interesting part is that WAT has another bulb -01 that is a 28V, 25W halogen that draws 1 amp at 28V. I have a 28V system but IPC still has the 303-00 14V lamp and not the -01 28V.
