I want to replace the 12 volt fluorescent fixtures on a sailboat. What problems might I expect? What about adding a dimmer?

Should not have any problems, they will work great. Watch what temperature you pick (6000K is very bright), but the dimmer will work.

I use these outside and haven't had any trouble with water I also added the wireless dimmer and haven't had any troubles either. This is the brightest they come

This dimmer is for 12 to 24 volts DC. DO NOT wire this to a 110 volt AC circuit. This is used in RV and Marine lighting powered off the batteries. If you are attempting to dim 12volt DC lights on your 110 v system you will need a step down transformer from 110v to 12v. The dimmer goes between the step down transformer and the lights. 12 volts in to the dimmer and 12 volts out that will now dim your lights. Hope this helps?

No problem working with a dimmer. I love the light but will caution they have a disappointingly short life for the price.

The Domire tube you are looking at says "40 watt fluorescent tube replacement" which would be a 4' t12(that is the old, fat, inch and a half tube) so based on that info I'd say no. I just can't find any good tech info for that domire led tube.

The voltage is 12v. I don't know the current, but it should be fairly small for the LEDs. I replaced the fluorescent tubes in my RV by cutting the input 12v cables and soldering the LED parallel light string directly to the 12v input wires, and they seem to work fine. The adhesive on the back of the string of lights is not the best. It works initially, but the lights dropped down on the diffuser after a while. I have not done anything about that yet, as they still work OK.

Absolutely. That's what I'm using them for--in a 5th wheel to start replacing all of the 12 v fluorescent lights. Just be absolutely sure to connect the red wire to the positive 12 volt lead, and the black wire to ground. (reversing the polarity on LED's destroys them.)

I'm not sure if there is such a thing as a 12-volt dimmer, but that's the answer if they exist. I'm not aware of any 12-volt LED's that come in less wattage than this one.

Not sure about LED replacement. Takes standard 12V bulb available anywhere. Just make sure same type/watts or it can melt fixture.

One of my outside lights connected to this switch is a spiral fluorescent. Not sure about the wattage off hand, but I think you're ok.

If you are replacing a Florecent lamp with an LED lamp, you must remove the ballast first, or at minimum bypass it. Bypass or remove any ballast that is in the fixture and run the lamp directly 12 volts DC. Find the 12 volt DC power source that is powering the original Florescent lamp ballast, unhook the ballast power supply, wire nut or crimp 12vdc power wire to red wire on lamp (bulb), and 12vdc negative to black wire on lamp (bulb). Install new LED lamp directly into the tombstones at the end of the fixture housing.

I bought this for a 4 ft. Fluorescent Light for an aquarium, which is why it's waterproof, this one will not work for dimming. They do make a dimming Ballast which will work, but it's dangerous and should be done an electrician.

Yes, it should work, if your system is 12 or 24 VDC (some are rated for both 12 and 24, some are rated for 12 volts only) and you are below the rated amperage of the dimmer . This is a PWM (pulse width modulation) type dimmer - turns on and off X times per second. They are usually 5 amps maximum. Heat is a function of load - as it dims, the load drops, hence, the heat will drop as you dim it. Also extends the life of the lamps.

Light Dimmers are not designed the same as motor, (fan), speed control. If you are using the light dimmer for LED or Fluorescent, the fixture and bulbs have to be designed as dimmable. They will be marked on the box, or in the instructions. Expect to pay a little more for these fixtures. If you are using these for Incandescent lamp dimmers look at the Amazon Wall Mount UL-listed LED/CFL/Incandescent Dimmer Switch 120VAC 60HZ 600W with top slider and on/off switch by TORCHSTAR for $9.99.

yes, this is no problem, as you remove the old light fixture (the rating is for that ceiling light). We bought this light about 6 months ago and absolutely love it. It comes with 12 20Watt halogen lights and is dimmeable.

They would have to have some type of ballast system to power the light. I would just replace the entire unit. There cheap. Mine seem to last about 3 years but i only run it on the weekends. I want to update to an LED in the future. Good Luck.

I think you would be better off to use an inverter with alligator clips to run lights with a 12 volt Marine battery. ( I am assuming these lights are interior lights.)

I used a lyton electronic LED dimmer. Works perfect I would imagine the old triac dimmers would not work well . . .
