La señora is so ecstatic about this she has prepared ten pounds of dried ataulfo mangoes, from her orchard for me. The lamp replaces a single tube 12-volt fluorescent fixture. The 11-volt fixture is waterproof (not submersible). Great to have up in the ceiling above a stove with simmering pots.
Now comes the installation of 750-lumen 12-volt LED "placas". 6,000 K, three dollars ninety five cents each. The days of incandescent and fluorescent are now like, prehistoric.

3 or 4 R5 Cree emitters should be able to pull that off running 700mah to 1000 mah @ 12 v. Not so sure how the newer U2's do for current draw and lumen output.
