What is 660W 250V?

edited May 12 ’20 at 21:10. Seems like 660W 250V is the standard rating for many UL-listed sockets, including silly plastic ones. Modern lamps have a fixture rating sticker (looked at two and one was 40W and the other 150W- and of course if you change the shade the rating might be different).

What light bulb is 660W?

What does 660 watts mean? In the US and Canada, nearly all homes are wired for 120 Volts. A 60 W light bulb would require a current of half an amp (using P = I V). If the OUTLET says 660 W, then it means that the maximum current that the outlet would tolerate is 660/120 = 5.5 Amps.

What does 250W mean on a lamp?

These LED bulbs use 30 watts of energy, but are very bright, putting out 3,000 lumens of light. The 250W refers to the incandescent bulb equivalent. So this means these bulbs draw 30 watts, but put out 3,000 lumens of light, the equivalent of a 250 watt incandescent bulb.

What is a lamp holder adapter?

What kind of batteries are in a lamp holder?

Is there an ul sticker on the bottom of a lamp?

There’s a UL sticker, but otherwise nothing else is printed or stuck on the lamp sides or bottom. Without any other information, you are left with trial and error. With an incanddescent bulb you need to be concerned about overheating the shade. With an LED bulb the concern would be the temperature of the control circuit in the bulb.

Is it OK to use a 60 W incandescent light bulb with an LED light bulb?

With an LED bulb the concern would be the temperature of the control circuit in the bulb. The 660 watt rating of the lamp holder would indicate that should never be a concern, other parts of the lamp will always be the limiting factors. Unless the shade is ridiculously small, I would think a 60 W incandescent would be fine and 100 W probably ok.

What’s the Max wattage for a table lamp?

You can use anything UP TO 660W, which for a table lamp would be ridiculous. Anything less than 660W is fine. The 660W rating you see is the rating of the socket component of the lamp.
