Working on a "street light" as seen on Ebay described as 30W LED Street Road Outdoor Yard Industrial Lamp Light Floodlight AC85-265V IP65?

It has a yellow wire/green stripe that is grounded to the housing. It has light brown and medium blue wires. wiring diagrams I saw said blue=neutral and brn=line When wired as such it works as a strobe as it flashes. The housing says 220V...which seems contrary to the colors of the wire. Is this light 220V only?


I think that might be for 220 - 240 Volt operation, only. The color codes sound like European / U.K., not U.S. (I am not expert in non-U.S. wiring.) Even in the U.S., industrial lighting is often built for 220 - 240 Volt operation, except you can often find fixtures that can be wired for a variety of voltages.

what i think happened -- you've gotten ahold of a product intended for installation in a country where the wiring standard is single phase, 220v. in those places [virtually everywhere other than North America, Japan, Taiwan, Philippines, and Korea] the single hot line [brown] is +220v to ground. I think you needed to order the US version of that product, which is intended to work on 110v. If you can find it, consult the maker's English language website -- LED lights might well work fine on 110v [I don't know] in which case the strobe effect is because there is a controlling switch somewhere that needs to be changed.

Your light will work with any line power from 85vac to 265vac. The power supply takes the AC line power and steps it down to a DC voltage that the control board can use. 220vac in the USA is the same voltage as 220vac in Europe and the rest of the world. HOWEVER, Europe uses 50Hz power vs USA s 60Hz power. Unless the appliance or device is time sensitive, these two frequencies have little effect. The color of the wire makes little difference. Just connect the line power to the proper wire (brown), neutral to the proper wire (blue) and ground to the proper point. The strobe effect is caused by the light sensor picking up the light from the fixture itself. The sensor sees the fixture s light (either directly or reflected from a nearby wall) and turns the light off. When the light turns off, the sensor sees that it is dark and turns the light back one. The cycle repeats itself at a rapid rate. Put a shield in front of the light sensor so that it doesn t pick up any reflected light. Don t block it off completely or the light will stay on.


Sounds like you have a light intended for the European market, which would explain the wiring designations. And if it is indeed intended for the European market, yes, that's a 220v fixture. Interesting that it isn't working, the AC86-265v rating indicates that it should work fine.




Seeing the blue neutral and IP65 rating almost assures it was meant for European markets, if it was made for the US it would typically have a white or gray neutral and bear the equivalent NEMA4 marking. The AC85-265 indicates it should work on 120 or 240vac. Does it have a photocell, motion detector, or dimmer? I worked on a couple a few years ago that the base model was multivolt, but the accessories had to be ordered a specific voltage or they didn't work right. You might get better help if you posted the manufacturer and model number.
