Alpenglow made the their rep many (20?) years ago Practical Sailor publicized their fixtures for having no RFI problems. If I was installing new, I wouldn't buy any fluorescent fixtures unless they were guaranteed not to have RFI problems, the cheap
stuff inevitably has RFI, or buzzes, or falls apart not too long after being installed. And while white LEDs and high brightness LEDs (the Luxeon stars are incredibly bright and small) have plunged in the last two years...they're still more expensive than fluorescent.
I don't think the selection of crimps and crimping tools can be overemphasized in a marine environment
. SPEND the $50 for a ratcheting crimping tool, and brand name crimps, and you'll never regret it. They just don't fail on you. The 500/$10 kit from the auto stores are usually split metal, but the better ones are tubular metal, or have tubular liners, and tinned or copper sleeved. Professional grade crimps, available in a kit from any electrical supply house, are damn close to the price
of Ancor fittings.
One year I splurged on a gift for myself, one of the fancy one-handed wire strippers that grips and strips all in one squeeze. These come from many makers in various qualities (avoid the cheapies!) but I'm also delighted with the time this saves. I've heard some folks complain this can nick some of the wire strands, but I've seen very little of that problem, less than any other approach. One shot, and the stripping is done and done to the length I need to match the crimp, in one shot.
When you've made a proper crimp, with the right wire guage to match the fittings, quality fittings, and a ratcheting crimp tool, you can ALWAYS do a gorilla pull on the wires afterwards and they'll stay put. Followed up with a proper seal (and I love those Ancor adhesive-lined crimps!) you'll be able to do the work ONCE and never worry about redoing it. Yeah, that costs more time and money
up front. Still cheaper in the long run.
