Yes, I was of course joking. I'm amazed someone took it seriously.

I wonder what the difference is between doing that and buying a post 1998 boat that needs a lot of work, or later sailaway that was never completed? I don't really understand the distinction between a boat that needs a refit and a sailaway.

Really, I've been using them for about 18 years and never had a problem reading under them and never had any eye strain.

They may not quote the figures on their website but they might be able to give you that specification if you contact them. As I've already said, Bedazzled are a supplier of quality LEDs so I don't think they would be supplying poor quality stock. I can't help thinking your approach here isn't really practical because even if you do find suppliers of 12v LEDs who supply colour temperature specifications you might not actually like the lights in practice. I think I'd be more inclined to buy one light, see how I like it and then either send it back for a refund or order more.

I don't know about broad spectrum, but the best supplier of quality 12v LED lights in my experience is Bedazzled. Bedazzled LED Lighting

Why? Assuming the boat has a working diesel engine then the whole escapade seems like an expensive folly. If the engine is knackered then it might make sense, but as others have said, if you must do this conversion then using a Nissan leaf battery is a bad idea. In the whole scheme of things it probably wouldn't save you much money compared to buying some proper, safe LiFePo4 batteries like Fogstars with built in battery management systems.

Given the choice I think that would the preferred way of many single-handers, it would certainly be mine. Unfortunately there seldom happens to be someone standing at the lock, windlass in hand, offering to work the lock for me. So using the roof is the best way.
