J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Masthead Tri-Color/Anchor light LED bulb replacement

I have an Aqua Signal brand series 40 tri-color/anchor stacked light fixture at the top of my mast. http://www.aquasignal.info/ecat/htd...y_id=1&product_id=48&item_id=338
The tri-color bulb is out and I am considering replacing it with an LED bulb instead of the 25 watt incandescent. While I am at it, I would probably change the anchor bulb also since the current draw is so much less.
My question is, has anyone used these bulbs and is the tri-color bulb replacement bright enough.

The above bulb has 18 led,s. There is also one on Ebay that has 63 led,s and the cost is less than half that of Dr. LED. Any thoughts on whether or not the less expensive bulb will do the job?

Not sure about the tri-color - which I am sure is fine - but as for the anchor light they work great.
