Notice: Cannot use for DC13V RV or Above DC13v,high voltage may very hot and Burned out! Is this happening to you all?

Hello, there's customer not measuring voltage use high voltage and damaged the bulbs ,DC12V Bulbs Burned when last long time input high voltage , we received some Burned bulbs so have to add a notice to recommend, some new RV over 13.5v or 14V ,can select our GRV brand AC or DC 12~24V LED bulbs if not sure the input voltage,thanks!

These lamp substitutes are resistively ballasted and I would not expect them to survive at any DC voltage above 15V. If radio frequency interference is not important, there are better choices efficiency wise and light output versus charging/discharging. A discharging 12V "house" battery is at 13.4 volts or less, usually between 12.6V to 10.6V (lower cutoff). These, or similarly passively ballasted design, are a "must" if you want use a HF radio with the lights on. I haven't had any fail and they operate much cooler than the 1156's they replaced.

I have been using this product in a 12 volt system and have not had a problem so far. I honestly don't know what these are good for if they don't work in a coach or any other "12 volt" system where the charging system can be as high as 14 volts. A car 12 volt system is the same around the world .... same as coach. Make sure you have a 12 volt system and not a 24 volt if you are burning them out.

My battery voltage is consistently about 13.75 volts. I retrofitted a desk lamp with one of these bulbs, it's on for at least six hours/day and i've had it for about two months. Maybe just be mindful of the "very hot" warning, and don't use it in a tightly enclosed fixture for an extended time.

The set I insatlled are absolute clean for VHF as well as HF. The other type of LED lamp, which uses a switching type regulator, RFI depends partly on the design and also how physically close the lamp is with respect to the antenna. Since VHF marine is FM and not AM, lamp switching noise appears as "desense" and reduces receiver sensitivity. Best test on LED lamps and RFI is to buy one and "sniff" it with an HT or scanner before changing everything over. No theory beats a real world test.

Yes the end led lights burned out so I ended up replacing them. 3 out of 12 lights.

saying 12V DC would cook it I would just try leave plugged into computer for long time see what happens if nothing betting the battery is shot

Truthfully,I have not used it with 12V DC but clearly I don't see a reason why will it not work as all it is doing is relaying the signal. Question is whether it can stay awake with 12 volt or not. I am not sure but I am certain it will not cause any damage to the unit by you trying 12 volt input. Hope this helps...

it will burn up,you could use a 12v. transformer to reduce the voltage to make it work.

Like another write said....forget joules...look at clamping voltage and get 300 or less volts. This has 500 and is almost worthless since most failures from a power company transformer can hit you with 440 and that took out everything in my house including a well...surge protected TVs included. Luckily if your handy with a screw driver and a soldering iron you can change the MOVs in most electronics and the device with work just like new...or leave take it out and you have it working but with no protect next time. This strip uses movs and one hit and it will be gone.

Yes, that's exactly what happened to mine too. I had a 120v one which I was pretty sure may not be able to handle the equipement I had - the filter, pump and heater. I dismantled my broken one and looked at the back and saw that it had a similar voltage rating to this one and so i bought this ... installed it myslef and worked fine for the last few months now!

I used it as 120v. I didn't see in the manufacturers recommendations that it could be used for higher voltage. While it is pretty sturdy, I would not takes a chance on overloading. Not only could that cause failure, but it could frt your plugged in electronics too.

Try higher than 12vdc. I use it on a 24vdc system, and have not tested until your message and it works OK.

On the stereo there is usually a plate that gives input/output specifications. Check the output of the transformer. Voltage is not the only issue. If wattage doesn't match you could burn up either or both components.

Hello. I used mine for a 12V system. I am looking at one of mine that I haven't used yet right now.. there is no rating on it at all! Strange! The terminals on the end are not very big, like for a smaller gauge of wire that would be safe for a relay application but not large enough for 110 house wire. It's actually made pretty nice. So..I'm sorry that I am not much more help. Good luck

I just tried 2 18350s witch were both about 4v so that would bump it up to 8v. It came on then dimmed out. Prolly has circut protect and won't allow above a certain volt or amp. Not sure witch but I would have to say it probably won't run on CR123a.

Please (call manufacturer to be sure) mine melted/popped also depends on what system watts you may have but play it safe call the experts Robert....good luck!

I use a 12v DC transformer at 2amp and the valve switches very fast and strong, so most likely I've got more current than I need going to it, but it works. Note that the coil will get hot, but I've not had any burn up problems.

You could, but I think they have another model that is specifically designed for DC... If I remember correctly for voltages up to 24vdc... I wouldn't use one that is rated for 12 vdc exactly, just for safety margin.

My whole housing melted connected to 15A circuit so I never got the chance to replace it. If it is not a must need return it for something that expressly states the Amps you need on the housing.

I called their number looking up on internet and they were very friendly. They would tell you quickly. They did inform me it will not function with less than seven amps from your dc. I found a loose wire attachment in fuse area and the new one I updated(they suggest replacing every five years). Once I fixed they intermittent three amp reading by tightening even the old one worked again, but safety trumps cost.

Not sure. Most RVs have 12 volt systems. Contact a RV dealer and see what they say.
