SeaVision underwater lights...upgrade to LEDs?

It's always worth going LED. There or anywhere else. You might even find you like the color options but mostly you'll like the quality of light and the reduced frequency of replacing bulbs. Just make sure you go with strong enough bulbs and the right type. I'm going to give that same answer whether in your home, on the boat, under the boat, or in a business. We've made very expensive changeovers in stores that in terms of the cost of bulbs or electricity may never pay for themselves or, at best, take years. However, the reduced annoyance of flickering lights or lights out and reduction in having to get someone to come in and change the bulbs only makes us wish we'd done it sooner. And the quality of light is great as well.

Caveat and full disclosure. While users of bulbs, we also do own a business that sells LED's so have some cause of prejudice. However, we got into that only after seeing the benefits. I will not disclose our business name as it's not my point to solicit business.

The HID's have a slightly brighter light. But burned out $75+ bulbs are quite common with them. Chances are you're going to need a $600 ballast in addition to bulbs on at least 1 of them. The LED's use less electric, don't burn out if you forget them on and run on plane, and last a lot lot longer. I'd convert them.......

I upgraded from the HID to the LED RGB and so far, I'm worried they are not very bright. I'm waiting to get out of my dirty marina and into some cleaner water at night to get a better idea. For $6,000 I expected more.

If you could find any local boat to compare to may help.

We have been pushing the Aqualuma line. Gads of installs and older unit upgrades.
Great LED packages.
Even in the dark Ortega water, you can see the lights well past the swim platform.
