They're back-ordered for about 10 days. Must be a popular item. Here's the manufacturer's data sheet http://www.aeroelectric.com/Mfgr_Data/Lamps/JKL_Lamps/ZLP-MULTI.pdf The item stocked by Jameco is 3.5" long by .48" wide and draws 350 ma at it's rated 10.2 volts. It's also said to have a max operating voltage of 12 volts. 3.5 watts dissipated into this area and volume suggests it's a POWER device with no particular power conditioning capabilities built in. I.e. it would best be driven by a constant-current power source (like the buck-pucks). Will know more about it when we can get our hands on one. Bob . . .

    Yes, Bob, that is the answer. Our Sportsman kit came with a supply of Monel rivets for the thin, stainless firewall. Dee On Thu, Mar 28, 2013 at 10:07 AM, Robert L.

    Yet there are many thousands of RV-x's flying with regular A/N aluminum rivets holding stainless firewalls to aluminum *and steel* structure. Many of them for several decades. Aluminum is primed; steel is either primed or powder coated (depending on the age of the kit). Things get bent or cracked occasionally, but I've never seen anyone on any of the user groups complain about rivet or aluminum corrosion in the firewall area.

    No, don't remember that. Ours were -3s and yes, and even then they were not easy to drive. Two of us did it holding the firewall horizontal over a bucking bar clamped in a vise.

    With primer barriers, particularly on the aluminum. Most sheet stock in use on kitplanes is alclad and doesn't generally need primer. All extruded angle and bar stock is not clad and needs to be primed to prevent corrosion. Many folks prime all faying surfaces (where two pieces fit together) and it should certainly be done at dissimilar metal joints.
