Leviton 660w rated plastic lampholder (back view)

Leviton 660w rated plastic lampholder (back view)

A back view of the lampholder. Not that much information on the back. I guess the school didn't send porcelain lampholders because they can break, during shipment. But yeah.

I have one of these, I found at the flea market, but it has a pull chain. Interesting this one has feed through terminals, mine only has one set, I guess since these are keyless they can switch more than one from the wall switch.

How far the screw heads (with wire connected under them) are from the surface on which the socket is installed ?

It looks like they're pretty close, but these are meant to go on an outlet box, and not surface mounted.

They probably sent you plastic ones because the plastic ones are cheaper. Trust me the plastic ones break almost just as easy. I've sent the screws right through the mounting keyholes many times because I accidentally pulled the trigger too hard on my impact gun. The keyless and pull-chain ones we use at work both have two sets of terminals.

I laugh at the 660W rating on these things. For the plastic sockets, it should really be more like 100W. These things turn yellow and brittle with anything more. Even 100W lamps make these get funky. I like the porcelain ones much better but they're fragile and since they cost more my boss won't buy them. Almost everything we install is LED now though so heat isn't a concern with these plastic things.

I'll have to look more closely at mine, it's mounted to an outlet box with cord so I'd have to dismount it to check.

This is a little off topic, but a lot of the newer pull chain ones are really hard to pull the chain on, esp Leviton's. The Pass and Seymour ones aren't quite as bad. But I found the GE ones sold at Walmart have the smoothest pull chain, partly because there's a big hole in the porcelain for it to come out of through an eyelet on the socket. I haven't looked at the Allied or Cooper/Eaton ones but they might be better too in that regard.

Back on topic, yeah I'm glad all of the ones in my house are porcelain. I collect the plastic ones too but if I was using them for any length of time I'd use porcelain.

IIRC my boss buys Allied keylesses and pullchains. Not really sure on the brand but they're plastic and have that ring around the screw shell that unscrews (so you could expose the metal screw shell of the socket; I guess if the lamp base gets stuck in the socket?) and our pull-chains don't have plugs on them.

My house had two keyless sockets in the garage and one each in the laundry and utility rooms. All porcelain. All have been replaced with multiple fluorescent lights except one garage keyless, which still has a 100W incandescent bulb.

I don't remember if the Allied ones have that ring or not. I think Ace sells them but I don't see many. I did see two keyless ones at Habitat today. I know my P&S ones do have rings both porcelain and pullchain and my GE one does. But I haven't seen any Levitons that have a removable socket. My P&S pullchains have the feed thru terminals like these Levitons.

My house has a Leviton porcelain keyless in each closet, two in the attic, and two in the garage. Most have a conical shape but one in the garage and one that was in the laundry room are flatter. I assume the flat ones were installed later. I know one actually replaced the original Miller fluorescent fixture in the laundry, that got moved elsewhere and we moved it back in.

Our old house from 1992 had a plastic one with pullchain and grounded outlet right above the attic access. I could see it from the floor and it didn't have a bulb. Of course by 92 these weren't allowed in closets so that house had shaded fixtures in the closets.

@streetlight98, not only its rated 660w, its also marked "600V" right next to the rated wattage number. Why would you use this on 600V circuits. Thats not even right!

I like LED, but in household use, NOT commercial use. 

I like HID lamps, especially the High Pressure Sodium lights, they have a orange color, which is actually my favorite color! Smiley  High Pressure Sodium High Pressure Sodium High Pressure Sodium

I think it's an NEC thing that any lampholder used on a branch circuit has to be 660W 600V rated, unless the circuit is in excess of 20A, in which it's a "heavy duty" lamp holder and must be 750W 1000V rated IIRC.

The dielectric rating of the housing must be for 600V...it's like insurance that the unit will withstand higher voltage, like 208, 240 or 277. It's not intended to be used on 600V. (In Canada, they use 3 phase 600VAC for industrial use...and only for phase to phase lighting.)

I've done that plenty of times too even with an electric drill it's annoying really.
I'd love to see one of these arc and spark and burn on 660w 600v because you know they will!!
