High Intensity Flush Mount LED Bolt - Customer Questions

Frequently Asked Questions by Oznium Customers

Can I power these with 24 volts? - by Tony
They are currently designed to run off a 12VDC source.

To run them off a 24VDC source, you could wire two together in series.
Or if you need at least a few hundred pieces, we can custom make them for you to handle 24VDC.
What is the wavelength rating for the UV bulbs? - by Justin (South Dakota)
You can find more details on the Technical Info tab on the product page.
What is the forward voltage of these LEDs? What is the ohm value of the internal resistor? I would like to build a circuit to adapt these to run off a 24V DC power supply. Thanks - by Anthony (United States)
Cool white forward voltage = 2 x 0.5W chips in *series*. Forward voltage is around 6.4V (~ 3.2V each). Resistor is 470 ohm.
Is the 3w version available in different colors as well? I know they are only in stainless.
We've been experimenting with a unique process to colorize the stainless steel housing in all sorts of exotic colors: red, blue, green, gold, and of course black.
The process is not cheap, and could easily add about $4 to $6 per unit.
As of now, we haven't decided to add it as a regular product, but are happy to custom build them if you can order at least a few hundred pieces.
Alternatively, if you can order at least a few hundred pieces, we could use the brighter 3W LED in a black aluminum housing.
I have your 11mm stainless LEDs. I would like to mount via a tapped threaded hole as I can't get to the back side of my project. I know they are M11, but can you tell me if they are M11x1, M11x1.25, M11x1.50 or M11x2.0? - by Jerad (San Diego, CA)
M11 x 1.0.
Can they be purchased with a plastic housing? - by Frank
The housing is aluminum or stainless steel. If you need 100 or more we could make them in a plastic housing.
Are these dimmable ?
I plan on using these as accent lighting in my soon to be child's nursary .. I hand painted a large tree on the wall and also built a few birdhouses . I would love to place these inside three different birdhouses on the wall and use them as night lights .
I have a dimmable LED decora switch that I purchased at Home Depot . I also have the LED dimmable transformer that has an output of 12v ..
Will it work or do need to purchase other resistors or something? - by Joe (Lindehurst New York )
They are dimmable but the dimmer needs to work with DC not AC. WE have this wall dimmer which is a dimmer: https://www.oznium.com/led-controllers/wall-mount-remote-dimmer
Good Morning...Just found info on your bolt lights..they seem to be just what I'm looking for..I intend to light the decks of my small bass boat..2 in front and 2 in the back..does wire length effect the brightness..should I run the same amount of wire to each light?
Cool, glad you've found the LED bolts :)
Theoretically the wire length will have an effect on brightness, but the human eye can't really detect any difference unless the length difference is 50 to 100 feet.
Don't worry! With even 10 or 20 feet, there won't be any significant brightness change.
I plan on using the 6mm warm white for some accent lighting in my truck console. They may be a little to bright, what resistors do you recommend using? Even though I plan on wiring these into the interior dash and console lights that are connected to the dimmer switch they may still be to bright. - by Mike
You can start with a 560 1/2 watt resistor and go up from there.
I love the look of these lights. I was planning on using them in a craft project. What kind of portable power source would be recommended for lighting these?
We sell a battery pack that will light these: https://www.oznium.com/install-bay/12v-rechargeable-ni-mh-battery

Or a larger battery could be used like a marine or car battery.
I have 4 of these, and 4 of the Pre-Wired Surface Mount 12V LED : 5050 SMD. I want to wire them all to a dimmer switch. So its 12V -> Dimmer -> LED's
Since they draw different currents, can I still wire them all together in a parallel circuit?
I'd like to wire one of these to a Raspberry Pi which has a 3.3v output from the GPIO pins. Is there an internal resistor in this product that can be removed so full brightness can be achieved with an input of less than 12v? - by Paul
Yes, but it might be hard to get to. You might be interested in this which can operate at lower voltages: https://www.oznium.com/loose-component-leds/led
I want to wire 10 of these together for low level lighting. I am using a 12vdc power supply but can only get the first 2/3 (very dim) working. Is this because I am connecting in series and it has to be in parallel? - by Grant (West Drayton, United)
They will be at full brightness if you wire them in parallel, thus giving 12v to each.
If you wire them in series, then the voltage to each will be the power supply voltage divided by the number in series. In your case thats 12v/10 = 1.2v which is not nearly enough to light them up properly.
Since you don't want them at full brightness, you can instead try wiring 2 or 5 in series.
Or if thats not giving you a desired brightness level, just wire them all in parallel and use an LED dimmer.
How do the 11mm cool white with lens compare to the led side view bolts in terms of brightness? More, less or the same?

If brighter, can you recommend another similar product ? I'm looking to make ambient lighting for my front porch that is dim but bright enough to see the keyhole on the door knob - by Alex
They are the same brightness. They would work well for your application.
I notice in the pictures some have a yellow face and others have a white face. What determines the face color? I'm looking to use these as a drl for my car but prefer the white look. I'm looking for the 11mm or 16mm cool white in color option. - by Alex (USA)
Led color sometimes makes the face of the led appear white or yellow. If you order cool white you will get a cool white color.
should I use inline fuse when wiring 4 11mm bolt LED's or just wire them directly to 12v source? - by Ken (United States)
If wiring to your car battery definitely, most applications it is a good idea to protect the leds.
Could I use these as turn signal remiders wired into the existing turnsignal wiring on my VTX 1300r motorcycle? I was thinking of mounting these on my windshield just below eye level to remind me to turn off the signal after turning. Would i need anything else ( inline fuse and such) . FYI I saw this on a youtube video using your led flexible strips. - by Joe (Palmyra, Indiana)
Yes, you're certainly welcome to use these as an indicator/reminder light. Doubt you'll need a fuse.
If I am connecting 3 11mm Blue bolts in parallel to a 12v source, do I need a resistor? - by Tom
No, resistor is already wired in.
will flush mount led 6mm fit in a power wheel mustang head light - by Joe (Gibsonia, PA)
Depends... how big is the power wheel mustang head light?
In case you want the conversion from metric to imperial:
6mm, 11mm, or 16mm (0.23", 0.43", or 0.63")
Can you use a dimmer?
Yes, you're certainly welcome to hook this up to an LED Dimmer. We offer a few:
Inline LED Controller
LED Dimmer Knob
Can these used as turn signal/marker lights on a vehicle?
Yes, you're more than welcome to use them for turn signal/marker lights on your vehicle.
Many people have used them for that with great results.
How about plain American measurements in Inches, thank you.
Also, maybe add 6mm to tech
Approx how much of the Back end can be cut off with no damage to light. - by Larry (Deltona, Fla.)
6mm, 11mm, or 16mm (0.23", 0.43", or 0.63")

You'll also see the inches shown on the technical info PDF drawings in [brackets] next to the mm.
FYI, if there's any measurement you want to quickly convert, simply type it into Google, and they will convert it for you. For example you can search, "10mm to inches".

Don't suggest you cut the back of the bolt at all. There's only a small amount of room before the resistor.
Would several of these mounted on the front of a golf cart be bright enough in the dark to see where you are going? Would they work on 16 volts? - by Gene (Burlington, Washingt)
They can work on 16 volts, but they wouldn't last quite as long.
Its subjective to say whether they'd be bright enough to see where you're going. If you're expecting them to be as bright as a headlight, then certainly, no.
But they will light up the path for a bit.
How about using a few of these 10W Modular & Stackable Cree LED Work Lights instead?
can i wire 4 in parallel with out a relay to my side marker lights
Does it come in pairs or a single piece? - by Shishir (India)
Sold as single units.
could you define waterproof? Can i submerge them underwater
You certainly can submerge them underwater since the housing is fully waterproof, with an IP68 rating.
What do I need to wire these into my house on a 120v switch?
Hello. I'm interested in using 12 of the 16mm (Cool White) for daytime running lights mounted under the front bumper lower grill. Would your recommend "No Lens" or "With Lens"?
With Lens will probably look a bit better for your application.
If mounted in a deck floor, should I be concerned that the lens or housing would break from foot traffic? Im trying to avoid counter sinkin - by Diego (monteal )
Should be fine. Its probably better to use the ones without the lens.
If I were to wire two of these (16mm warm white) in series, with a supply voltage of approx. 14V, would I require a resistor? If so, how many ohms? - by Mike
If you wire 2 in series on a 14v source, the voltage would be halfed to 7v each.
You wouldn't need any resistor at all. The brightness would obviously go down.
Since these are 12v, can I tap an existing bulb in my interior? I want to use them as cupholder lights and want to tap the shifter indicator light so that the flush mounts only come on when the lights are on. PLan is to wire 3 flush mounts.
Yes, go for it!
Any plans to make these in RGB? - by Tony (Cool Ridge, WV)
We'd love to, but it will require quite a bit of redesign, and not sure yet when we will have the RGB ready.
How many do you need? If you need a few hundred, we'll push the plans faster.
If I buy the one with the lens can I remove the lens? - by Freddie (Cool Ridge, WV)
The lens is simply glued on. You're welcome to remove it.
Can they be wired to act as brake lights and running lights - by Reid
Yes, its certainly possible. You're welcome to wire pretty much any LED to act as such.
If wireing multiple light should it be in parellel or series - by Fred (Vacaville ca)
Parallel! Series wouldn't make sense.
If you don't know what the difference is, here's a diagram.
Are the LED Bolt lights 12volt and can they be wired directly to a battery? - by Stanley (thunder bay ontario )
YES, they are 12 volt, and they can of course be wire directly to any 12 v battery, 12 v power source, etc.
What guage wire does this come pre-wired with? - by Dennis
What is the mounting depth? - by Dennis
Please see the technical drawings which show all the dimensions on the "Technical Info" tab.

For the 11mm, the mounting depth is 18 mm (about 0.70 inches).
For the 16mm, the mounting depth is 22 mm (about 0.86 inches).
