What voltage are these suitable for? I purchased these to replace some LED's on my motorcycle. (12 volt). but these blow up on a 9 volt battery.

The specs on the LED web page say the LED is rated for 3.2 - 3.4 volts & .02 amps. 9 or 12 volts is way too much. You need a resistor in series with the LED. For 9 volts use a 285 ohm resistor, or as near as you can find. For 12 volts, use 435 ohms, or as near as you can find.

Each led is rated for about 3 volts at about 20 mA. In order to run them from a 9/12 volt voltage source the led requires a resistor wired in series.

MattThese will work on no more than 4.5 volts.........real bright..........sorry i'm late....the other i bought from another company which i was testing were 12 volt they work nice.....but i bought only 6 for a test...........You would need a resistor to use those "the blue" to lower voltage to 4.5...........Rick

update...........Matt use only 3 volts.......4.5 was bright but didn't lastRick

If these were 12 V halogen bulbs, yes. Please make sure of that otherwise your LED lights will be destroyed.

HI, I used them for my trailer, it works good, I had to put a pair per side for stop lights, turn light and midium light, so I suppose they will work anywhere with 12 VDC.

These batteries are for cameras. Doubt if they're intended for flashlight use. Flashlight batteries are usually 1.5 volts and these are 3.7 volts. Go figger...

They are 12 v for sure am running them off of an Malibu outdoor landscape transformer which is only 12 volt can't answer about being able to dim as I use them for indoor ambient light against a wall

These are for low-voltage only. they are not for use with high-voltage circuits. You should not have a problem because the lights do not have a photocell attached.

Hmm I have the same ones and they work perfect for me. It sounds like you may want to try to get your waranteed. When all the led's are lit these are super bright.

I have these installed on my 36 volt golf cart with a 12 volt transformer. Not sure of the degree but they are just as bright as my car head lights in pitch black dark. I would buy these again.

I purchased these lights to use as replacements for dash lights on a motorcycle. They have the resistors installed for use in a12 volt system. They work fine in that application. Used singly they may not provide enough illumination for yard use. Set up in a multi bulb weather tight fixture with proper voltage supply they may work

we use the brightest 3528 SMD LEDs for these GRV brand LED Bulns,It about 95~120 Lumens when work at DC12V ~13V ,but Cann't use for more than 13V DC ,maybe become very hot more than 13V and short lifetime,maybe too hot and will Burned soon if input voltage above 14V DC,Someone said Burned out soon due to some new RV output about 14V Voltage,please confirm voltage is about DC12V when install it,thanks! thanks!

As far as I know, these rellays are 12 volt. In anny event, they are automotive, so will handle a range of voltage. They work fine n my truck.

The SMDs (LEDs) work on 3-3.6V. The current draw is between .02-.03A. There are 12 of these on each bulb. If you take the max values it comes to 1.296W ( 12 x .03 x 3.6). There might be some resistors that might be drawing some power. But overall you are doing way better than the factory bulbs. Update: I did a google search on these LEDs ( 1210). Vendors mention a consumption of .08 W per LED. For 12 it comes to .96W ( 12x.08).

Hello my friend Ernesto, Kindly note that the input voltage for this downlight should be 100v-145v. It's not in 12 volt. If you want to get LED lights in 12V, I would recommend you to consider MR16 LED lights, which are in 12 volts. For more details, you're more than welcome to contact Lemonbest freely. We're always here for your help. Nice day. Regards Lemonbest

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)

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

these LEDs are dimmable for most applications. lowest voltage is around 9v assuming these are 1.8v LEDs. a current limiting resistor is soldered onto the boards. the dash light dimmer works for the LEDs and they are much much brighter than the old incandescents. however blue lights are hard on the eyes when using them as a flashlight. use white leds as they don't distort the color of what your looking at.

I used the bulbs in a vintage Mercedes Benz. I have zero experience with motorcycle lamp applications. Sorry mate.
