Thin Line - Interesting. I know you will enjoy this for a long time. Its curious why its specs their replacement bulb specs are so different.
BTW, I have IMTRA and Marine beam. It looks like they were made in the same factory. At the time, I happened to get a really good deal at the Strictly Sail Chicago show from Imtra for the cabin

now than when we started researching this 5 years ago. Prices are about half now. Even a few good ones are showing up in Home Depot but you need to compare based on lumens per watt consumed. I think that many are using choke resistors and other junk tech to regulate current
