Will these operate on as low as 6v DC? Are they grounded through the case or with a separate wire? I'd like to use them on 6 volt positive ground.

Thick heavy one piece billet aluminum case, approx 2000 lumens bright white with 2 wires(black/red) installed on a rubber bumper 12 volt car. I am not an electrician you can call CREE for that but it should work on 6 volt probably not as bright. Some LED's can only be connect one way or they will not light but you can give it a try with a positive ground

No, the voltage range is rated as 10V to 30V and it may run as low as 9V but if it produces any light at all at 6V it will be very dim.They are not case grounded, rather a separate wire. However all you would have to do is terminate the ground wire with a ring connector and screw that to a ground point on the chassis of the device providing power, assuming that device is chassis grounded.

The ones I have are 120v single phase. Wish they were 220v. That is standard here so have to use an inverter. I am using them in a factory in the Philippines on a tracer machine. They have been run hard 6 days a week for 6 months with no problems.

They need dc voltage. Not sure how you are using them but if you have ac (alternating current) you will need to use a transformer that converts it into dc (direct current). I used them on my golf cart witch has 12 dc so all I needed was an in line fuse.

Most led's like this will run at a varying voltage. Usually this style will work with 4~18 volts at least. They may run slightly dimmer but it will most likely be not noticeable. If you would like i can go hook mine up to a 6v DC power source and see how they act. ( i bought them from here, decent lights, not the best of quality, wire isn't copper and a very very small gauge. I soldiered my connections because i was worried about the wire just breaking off without the insulation on it.

They don't! I have all 6 in my garage ...voltage is too high...not sure what they are meant for. Had to buy six more at a local battery store earlier this summer

I don't know if they have a 6V model. I would contact the company as I would be very surprised if they didn't have what you are looking for.

Yes if you wire them correctly u can do that. There are different ways to connect the batteries. But are you using 24v. Most low voltage is 12v. Im no expert or electrician. Just based on experience

They come off the charger at almost 4 volts, so they may trigger any over-voltage circuit. I couldnt use them for my intended purpose , but they are okay on small weaponlights, but not surefires.

I bought the ones for the UK and they were grounded. It appears that the Type L ones are grounded as well.

Doesn't matter how you wire them since the driver circuitry has an inverter bridge. They can run on 12V AC or DC. I believe the wires are black and red so following convention I wired black to negative and red to positive.

These run on 12v direct current. You need to install a 50e max 120vac-12vdc transformer to do the job

Not sure because there is a circuit board attached to them, but the plug is 110V.

The ones I used only had a blue and brown wire and the brown is positive and blue negative. The unit will also work on 12 VAC since there is a circuit inside to rectify and filter the power to 12 VDC. So, I suspect that this new Green/Yellow wire is for ground. I had several of these circuits fail because I was using in in a 12VDC system with a charging circuit that would take the voltage up to 14.5 VDC. You can allow for this if you add a 5 ohm/5 watt resistor in series with either the blue or brown wire.

Not low voltage. I did not look to order the posts as I need different sizes...

To keep from shorting out the circuit I would disconnect the negative grounds just to make sure. These are also very low voltage; the bigger the battery the longer it will take to bring the batteries up to full charge.

These are for 12volt. Might be able get 6v LEDs but not sure. Hope this helps.

They will not work on Ac voltage. A rectifier may work. You will get some voltage drop. Depending on how many feet you are running it may not affect it too bad. Won't hurt to try. You may have to add a filter cap too. 12 volt DC supply's are cheap though. I'd just buy one. You don't need a big one. Low current draw with LEDs.
