this website has a wealth of information and after browsing for quite a while I cant seem to answer my question. I am interested in selling an LED PCB light in the US. It operates on 24v1amp DC powersupply and the light has a total wattage of 20watts. It also has a dimmer with temperature control. The dimmer just so happens to also emit a few RF frequencies for wireless controll which I actually dont need. Its says it has these optional output frequencies: 0.5K、1K、2K、4K、8K.

So my question is I have a very niche market maybe 100 of these products per year. So obviously 20,000$ of testing is simply way out of the question.

I'll be honest what do I need to do to sell this product with no testing!?

The powersupply 24v1a switching powersupply. Is it legally required to have FCC.

The Dimmer with the RF frequencies must have FCC approval?

And finally the LED pcb board does it need any testing?

Secondly, The Dimmer actually may already have FCC approval from china im not sure if it is legit though(Ill have to investigate that further).. IF it is approved do I still need to test the entire system for FCC approval or is it sufficient just to have FCC testing on the dimmer. Basically I am interested in the cheapest possible method of selling this low margin low volume product to a few of my friends in interest clubs.


I would like to ask about the verification. From what I have read my product needs just FCC verification. And this can be completed by any testing facility in the US or foreign country with good standard of practice I believe?

    \$\begingroup\$ Yeah, well - you kinda said it yourself. I don't know the FCC rules, only the European ones, but if you plan to manufacture or sell equipment that is required to have FCC approval, then you will have to do some testing anyway. You might get away with easier tests by using pre-approved power supplies and sub-systems, but as long as you have added any custom hardware then I would be surprised if you got off without having to test at all. \$\endgroup\$ – MrGerber Jan 14 '18 at 17:48

    \$\begingroup\$ That being said, I don't think the chance that government will notice your low volume product is very significant, so there is always the possibility to just not give a shit. Not that I will recommend that in any way, of course \$\endgroup\$ – MrGerber Jan 14 '18 at 17:52

    \$\begingroup\$ "The dimmer just so happens to also emit a few RF frequencies for wireless controll which I actually dont need. Its says it has these optional output frequencies: 0.5K、1K、2K、4K、8K." these are audio frequencies, not RF. If the device doesn't have an RF transmitter in it then it is an 'unintentional' radiator. \$\endgroup\$ – Bruce Abbott Jan 14 '18 at 19:17

    \$\begingroup\$ (Also, as previously stated, those are not RF frequencies. You don't even seem to know what the device you are selling does!) \$\endgroup\$ – immibis Jan 14 '18 at 23:40

Compliance is not trivial. If you do not have the resources or knowledge to form a basic compliance plan, you cannot hope to pass any certification requirements. The FCC is not responsible for helping you with this process. You have to show them why/how your product complies with the applicable regulations. Determining the applicability of regulations can require minute attention to the details of the design. We do not have enough information to tell you which regulations are applicable without seeing all of the descriptive, controlled data that defines it. We would also have to review things like your manufacturing process to ensure that there are no process-related concerns that could affect in-service noncompliance.

If you're serious about this, you should consider hiring a Certification Engineer who knows how to do it. Depending on how much you value your time and sanity, that may well be the cheaper alternative.

Alternatively, you can start reading the regulations themselves along with their associated guidance materials. Be warned, this is a career. Start here:47 CFR 15 https://www.ecfr.gov/cgi-bin/text-idx?SID=6d3d77d9dbd8f9fa37744461b91d1dbe&mc=true&tpl=/ecfrbrowse/Title47/47cfr15_main_02.tpl

    \$\begingroup\$ All regulations exist for a reason. Electromagnetic pollution is pollution. If you produce and sell a device, it can't be allowed to pollute significantly. Would it be easier for companies of any kind to sell their products without regulation? Yes. Would it result in increased pollution? Yes. Regulatory compliance is important in formal professional engineering practice, as in any other. \$\endgroup\$ – vofa Jan 14 '18 at 19:39

    \$\begingroup\$ Maybe, but regulation also tends to be heavily influenced by big industry players who can afford large compliance departments, lawyers etc. It helps keep the man in a shed out of the marketplace, or force him to sell to an already existing large company. One could argue that the internet should have been fiercely regulated from the start and if so, it would never have flourished, because two guys in a dorm room with an idea would have been defeated by the compliance costs to prove their "Google" should be allowed to exist. It is very debatable whether all regulations exist for a reason. \$\endgroup\$ – Ian Bland Jan 14 '18 at 20:06
  • \$\begingroup\$ I agree its good and bad. But there should be more flexibility for startups. \$\endgroup\$ – Steve Stein Jan 14 '18 at 20:35

    \$\begingroup\$ It's difficult, but regulatory agencies cannot give special treatment based on economic situations. It is irrelevant to compliance. \$\endgroup\$ – vofa Jan 14 '18 at 20:41
