will these leds run on a 9volt battery?

I haven't tried with 9 volts but if you intend to use a 9 volt battery better connect a resistor in series, there are guides on google to calculate the the value of the resistor to be used!

If I recall correctly from when I installed the unit, it should be a 9v battery.

no, they over charge to around 4 volts and may fry your light.i tried them in my poly tac 90

They should work fine... These LED'S are a bit bigger then you standard bulb. Just make sure to get your positive and negative right or they won't work.

For the receiver, yep, they devour 9volts. I used to get about a week out mine before i plugged them in.... newer models (wrl-b?) Have a 9v socket so you can plug them in. I''ve also wired a 9v battery connector (from radio shack) to a power supply (red neck engineering) for a unit that didn't come so equipped. I use mine for varmit sensors and don't have much of a need to go moblie for long periods, so it works for me. As for the sensors, I''ve picked up lithium ion rechargables from Amazon... My sensors can run for 3-4 weeks... Happy hunting!...

These are SMD LEDs, which are designed for 12.0V-DC. The will, however operate on as little as 9V, up to a maximum of 18V before damaging them. They are DC ONLY! Running on AC current will damage them permanently. Also, 16.4' utilizes roughly 24W of power, and requires 2A output minimum on the power supply. If you are running these from the RV battery bank or the alternator, you will have more than ample power to supply several of these strips nightly. I am running six strips of these lights, one of them 24x7 from a bank of two 100Ah deep-cycle batteries, and the draw per day is only 12% of my total off-charge capacity daily. One strip can be ran for 4-days or more, without recharge! In an average RV setting, 4-6 hours per night, two batteries will supply the several strips for a week without need for recharge.

They work on any 12 volt battery system. They are a very bright white light.

Yes. They run from 12v dc so a battery would work fine. Run-time will be determined by your battery size/capacity... you would need a battery of sufficient size if you plan to run these very long or if you want to run multiple strips (think motorcycle or car battery).

These LED bulbs will light properly even if you switch POS. & NEG at a battery. The polarity is directed correctly internally with diodes in the regulating circuit. Therefore they would light if you were to use AC voltage. However, I would not recommend AC without consulting the bulb manufacturer because 12 volts AC is 12 volts (average) RMS. The peak voltage would be much higher and could possibly shorten bulb life significantly.

Yes. They are 12 volt and can be run directly off the battery. I currently have eight running off my battery bank.

I use a 9v battery. You will need to adjust the battery connectors a little, as it tends to be a little wide.

Nope, any 9v should work. I'm using a one spot power supply on it right now

Not sure. The tag on the light listed a wide range of voltage 9 to 60 volts DC. I think it would run one of them as it is within the voltage range but I do not know how long it would go before running the battery down. This light is very bright but is a wide beam and not a spot. I have them mounted on my DR 650 trail bike but not hooked up yet as I am going to convert to LEDs as much as possible to save power and have the extra for other things.

Yes, they are standard 9 volt batteries. They are just the professional grade Duracell.

These are 12 volt. Only 3 LEDs worked on the ones I got, I wouldn't recommend these

Not directly. The motors are 3 volt motors and if you provide higher voltages, the motors will be damaged over time. The kit comes with a battery holder for 2 AA batteries. If you absolutely need 9 Volts, you can either look for 9 volt replacement motors or use an inexpensive voltage converter. These guys http://www.pololu.com/ have a great selection and they may even have replacement motors.

These are 12V (probably AC only) If you will have transformer to 12V they will work technically. If you have an isntallation with multiple MR16s and you would like to change it to LED I would recommend to change the transformer to LED version. Otherwise it may not work or if it will work you will decrese the lifespan of the bulb (I work for LED manuacturing company in EU)
