The first video you made about this was interesting to me. I don't have a 3D printer so I looked for a way to build something similar. I have a different battery so I couldn't buy one from you. I found some stuff laying around and made something that works. I also made a shade out of a bleach bottle and one of those old fashioned clip-on shades. The only thing I had to buy was bulbs. Cost was about $5. It's not pretty but it works well.

Did work with electric vehicles in the past running a 24v dc to dc converter. We found out the led lights with wide ranges use multiple transformers inside, and switch between transformers as the voltage increases. You can see this in your test of the 11-30v bulb as the current had steps where it jumps. On the lights we had, our dc-dc converter was at one of these transformer steps and it caused the lights to flicker.

Great video Ben :>) 3 thoughts here, first, the bulbs come in a variety of thread sizes and maybe you should mention that you used the E26 fitting. This will help others to find the right size threaded bulb to get. Also, for those of us that can't/don't 3D print, you can find a Ryobi adaptor to save the 3D printing issue. Third, I have on my channel, a couple of videos about how to make your own adaptor easily with some PVC, scrap plywood, and the ryobi battery clip. The Ryobi clip and the adaptors are available on Amazon, Aliexpress, & Ebay. If you can't find them, I can help you find them. I would also tell you that I appreciate channels like yours and mine that give helpful info for others. Keep up the great content, Ben.

I can see how some viewers and commenters could make that mistake; it's (incorrect, but) easy to assume everything with an E26 screw base is/should be 120VAC if one hasn't seen it used at any other voltage before.

I wonder how many ppl blow out their 12VDC bulbs but accidentally screwing them into a 120VAC socket. Maybe make a video testing over voltage protection...? Have a fire extinguisher handy haha

The CFL bulb I showed was an old one. I really don't remember seeing any CFLs in the stores lately. They were a step in the right direction in terms of saving energy, but really just a brief bridge until LED lighting.

So basically it's safe to run 12v lights on 18v battery? I have a 12v led strip light that I want to run on a 18v power tool battery in my kayak, do u think it will be ok? The adapter has a green fuse build in on the red wire?

Most 12V electronics will actually run just fine on a RANGE of voltage. Many will run just fine on an 18V battery. If it's inexpensive electronics, I'd just try it. If it's something more expensive, I'd try to see what components it's built from, and make sure they can all handle up to 20V.

I have installed 1141 compatible LED bulbs in my camper (12V 1.7watts the packaging said). I was thinking of using my makita 18v battery. Would this work safety without having a 18v to 12v converter?

@@BenjaminNelsonX DC has greater line loos than AC, So using an 18volt battery for 12 volts means I can easily use a 50 or even 100 foot extension cord without dropping below 12 volts. Try it, it would make a great video. You can use your bench power supply.

so you have a 12 volt dc bulb that will screw in to a standard 110 ac socket, what could possibly go wrong, their will be morons lining up to do that because they won't read the bulb before screwing it in their house socket, any one saying won't happen is dreaming

I'm not aware of any light bulbs that actually require AC current. If it will run on 120v AC it would run on 120v DC just as well. LEDs actually require DC. LED stands for "Light Emitting Diode" and diodes only conduct current one direction: Thus DC. The LED bulbs that screw into an AC light socket usually rectify the AC to DC anyway.

How long would the bulb run before the battery dies out?
@BenjaminNelsonX
Жыл бұрын
That would depend on the capacity of the battery. The bulb is rated at 7 watts. That's approximately half an amp of draw, so a 4 AH battery could run it about 8 hours.

I’d open the bulb and see if it has a constant voltage/current circuit. The last bulb might not last on 30V

I haven't cracked either bulb open yet. I'm not much of an electronics expert, so it's hard for me to really understand all circuits just by looking at it. I think that 30 probably is kinda high for the Bluex bulb. The LeMeng battery specifically lists 30 right on the box. It also just feels a little higher quality. The diffuser is better.

Yes. The EXACT top voltage that a particular battery charges to might vary by manufacturer, along with any little trade secrets they have, but "18V" batteries usually have a charger that provides 21VDC.
