Using a 9v on LEDs

Been scouring the manual but still not sure.

Can we run a small bank of LED lights on our robot off of a 9v battery. It would be total separate for all other electrical circuits. Is it legal? It would sure save us some hassles. Thanks for all your help.

WE found that in R20 and R21, my question is does supplying 9v power fit unto the "Etc"

R 21 Additionally, batteries integral to and part of a COTS computing device or self-contained camera are also permitted (e.g. laptop batteries, GoPro style camera, etc.), provided they’re only used to power the COTS computing device and any peripheral COTS USB input devices connected to the COTS computing device and they are securely fastened to the ROBOT.

No batteries other than those allowed per R20 are allowed on the ROBOT, whether or not they are being used to supply power.

Does a 9v light system fit into the "ETC"

Thanks for all your time and help

Re: Using a 9v on LEDs

You would have to convince your inspector that the LEDs are either a computing device or a camera, and that the 9v battery is integral to it.

Since they don't compute anything, and they are not a camera I don't think they fit the first part. Furthermore, I doubt that they came with the battery integrally installed so they therefore don't fit the second part.

Anyway, that rule only applies to COTS devices, not devices you make yourself.

This is my interpretation of the rules and is not official, but I hope that it helps.

I would be a little surprised if the LED's you want to run fulfill this requirement, so if the LED's can run off five volts do that, if they can't buy a 9V voltage regulator and run 12v from the pdp or the vrm (I would use the pdp, but I don't know what exactly your using the LEDs for) to the regulator then to the LEDs.
If they are wired with a 9v head, and you don't want to cut it off, buy another from radioshack or somewhere and pair them.
