Converting Fluorescents to LEDs

Our engine room has four 110-VAC 48Ē fluorescent tube fixtures (8 bulbs). Itís really bright in there when weíre on shore power or running the genset. Besides the raw lumens, the long bulbs reach every corner so almost everything I need to work on has plenty of light. The downside is that the 110-VAC wiring external to the fixtures has several dangerous looking taped-up splices, is fed by extension cords and looks like crap.

There are also four original 12-volt dome lights that are totally useless mounted very close to the fluorescent fixtures. Iím thinking of ripping out the AC wiring, removing the 12-volt dome lights, converting the fluorescents to LEDs with something like these LED Replacement for 18" 12v Tube Lights and powering them with the wiring that used to power the dome lights. (The link has a misprint, but takes you to the right place.)

Has anybody done anything like this?

I know there are also strip lights I could run the length of the ER; not sure Iíd get the level if brightness I want (like below) or how the strip lights hold up to ER temps and voltage fluctuations.

I'd clean up the AC wiring mess but I would not get rid of the 110 V AC lights. I'd add 12 V LED. That way you've got light no matter which electric system you're needing to disable for the task at hand. For example I just replaced my house bank and cleaned up a bunch of wiring. I had to do it by drop light and head lamp. Far from ideal.

In a previous motorhome I replaced 12V fluorescent tubes with inexpensive LED strips but had flickering & failures after awhile. I finally replaced them with LED tubes by bypassing the ballast. They worked much better. I didn't find them on SuperBrightLEDS website
but I do see these complete fixtures that look comparable and decent cost.
Specs list 12-36V so higher charging V shouldn't be a problem, Oper temp up tp 130* F and output of 500+ lumens / ft seems plenty bright. Some of the positive reviews are for boat ER lighting

Nice looking ER - I am envious!!!

Appreciate your thoughts. To me, it would make sense to keep the 110-V fixtures if thatís the only way to get really bright lights in thereóand when the boat was new, that was probably the case. But with 2000-lumen 12-volt LEDs available now, I think I can simplify and remove the higher voltage system.

Great! Good to know youíre happy with the fluorescent tubes.

Thank you both.

One of the first changes I made to our DeFever 44, same as angus99's, was to replace the flourescents with LED tubes from Marine Beam. It required bypassing the ballasts, a simple rewiring. When I removed the coover to expose the ballast on one of the three fixtures, I found it to have been badly melted from overheating. Not good. Anyway, it is now very bright in the engine room and a lurking hazard was removed to boot.

Ian (angus99), I would fix the bad 120VAC supply and consider the Marine Beam product.

Our boat had 6 12V dome lights in the ER. Replaced them with LED light bars (about 20") and have much more light. Might still add a few more. And I love the Defever 44 ER's - had a friend with one on the Gulf Coast. And we saw Stella Maris this fall when we stayed overnight at your marina on the fuel dock wall, on our way up river.

Thanks, Charlie. Iím afraid you saw her at her absolute worst! Cosmetics start in a month or two, once we finish all our winter projects. Sorry we missed you.

Just replaced 48"tubes with LED tubes that work with old ballasts. Very bright and simple install. No new fixture or rewiring needed just put then in place of the old tubes. Inexpensive as well. Got them at Lowes.

in the process of doing the same thing now
installed one 48 inch Flor. 2 weeks ago and 'wow' talk about bright
we will be doing the other 9
With the emergency lights we will replacing the old 24 Dc lights with LED also.
No need to change out the wiring just fixtures.
in your case I would just clean it up

I just added a pair of the less bright (model E-360 I think) Scandvik LED fixtures to my engine room for more light outboard of the engines. They're pretty bright, although not to the level shown in the original picture.

Having 120v engine room lighting might be nice at times. Mine are all 12v and I've had a couple times of working with a drop light, flashlight, etc. or having to do some power re-configuring to keep the lights on while doing electrical work that required some or all 12v power to be turned off.

I've been slowly replacing my 110 VAC fluorescent bulbs with 110 VAC LED replacements in the engine room and boathouse.

I buy the kind where the ballast is bypassed. More efficient.

The bulbs are available from electric contractor supply stores not HD. The led bulbs are available in several brightnesses and color temperatures.

The ballast bypass LED bulbs are less expensive than the LED bulbs that work with ballast.

Four-foot LED tubes from Marine Beam are $29 each. That comes to $174 to replace the flourescents in three double-tube 48-inch fixtures. Ian, in your engine room I can assure you the result will be a very brightly-lit place. By-passing the existing ballasts is well within your skill set.

In an amazing coincidence I just stumbled onto these replacements while making an Amazon purchase:

I just replaced the 48 48" flourescent tubes in our garage with Hyperikon LED tubes from Amazon. About $10 each. https://amzn.to/35volng I pulled the ballast out of all the fixtures and rewired them. It took about 5-8 minutes per fixture.

I have four remaining tubes to replace on the boat. That's one of my projects for this weekend.

I'm in the "Get rid of the AC wiring and go with DC lighting in LED". I'm all for redundancy where redundancy is needed, but parallel circuits in differing currents really is a "Belt and Suspenders" solution.

To me that would look like a sloppy retrofit and visions of a TV sitting on top of a TV analogies start popping in my mind.

Thanks for the ideas and links, all.

Iím going to give a couple of these a try.

https://www.superbrightleds.com/more...00k/3654/7651/

They have high light output, operate on 12-36 volts DC, have an aluminum base, draw 1.23 amps per fixture and up to three of them can be linked together end-to-end. Also, they have a very small footprint, which will increase headroom in the ER. Finally, theyíre cheap compared to some of the boutique brands Iíve priced.

If they work, Iíll order up to six more. If they donít, Iíll return them and keep looking.
