Anchor Light replacement

Hi!

I am told by my yard that the anchor light atop my mast is corroded and the
entire unit needs to be replaced - not surprising as it has been up there
for 22 years.

As Cakewalk has no shore-power to recharge her batteries I've been looking
at replacing the heavy power-drawing lights that are typically used when the
engine is off (running lights, anchor light, eventually some interior
lights) with LEDs.

I was wondering if anyone has any experience with using a "replacement" LED
bulb (such as a Dr. LED bulb). I am considering, due to the cost factor, of
purchasing a new Aqua Signal 40 all-around anchor light unit (cost est $50)
for the top of the mast and using a Dr. LED all-around white LED (cost est
$45) to replace the included incandescent bulb. Total cost est $95 versus
$200 plus for the Aqua Signal LED unit.

Though Aqua Signal recommends not to use LEDs with their incandescent unit,
voiding the warranty if one does, it appears that this should work as the
Dr. LED bulbs claim to have built-in voltage regulators to prevent
shortening the life of the LED due to voltage fluctuations/drop-outs.

If this is a viable option for the anchor light, then I should be able to
use the existing running light and stern light units with LEDs too... yes?

Please let me know your thoughts/suggestions if you've had experience (good
or bad) with this set-up.
