I use both around the house. I have the LED things in wall lights and
table lights around the house. They are a bit small for general use.

C. Crane company has a good selection of LED type bulbs
http://www.ccrane.com/lights/led-light-bulbs/
They are more focused on 110v to replace standard incandescent but have a
few 12v.
Not sure i'm ready to spend $70 on one light bulb

7 watts - 520 lumens rated at 50,000 hours

Exactly. 520 lumens is no a lot of light for general lighting.
But the LED trick is to focus the light into a smaller spot in order to get
the lumens up and make it at least useful.

Nominal Lumens Watts Rated Life
Cool White: 520
Soft White: 398
Warm White: 355 7 50,000 hours
355 lumens is even less light. For a boat these may be OK for spot lighting.
