Another typical miniature base series wired outfit from the 1920s. The set uses Japanese tungsten filament lamps that had poor paint adhesion.

Although in a box nearly identical to the one from Brite Lites above, these two companies are not connected in any way

This is a battery outfit, intended to run from radio storage batteries or liquid filled battery jars. Sets like these were sold to farm families who did not have city electric power. The set uses the same box cover as above. The lamps are 6 volts each, and the sockets are wood.

This set by Dealites features their newly-patented "constant Contact" spring loaded sockets, that reduced set failures because of loose bulbs. The close up to the left is from the box lid, and shows the details of the new socket.

A most unusual outfit, designed to solve the "if one goes out, they all go out" problem with series wired lights. The control box allows the user to simply turn a knob when one lamp went out. The device bypasses one socket at a time as the knob is rotated, until the string lights again. Once the string is lit, the burnt out lamp could easily be seen.

Here's a set of figural lights by Premo. The Premo name was used for Christmas lights for only one year, so it is easy to date this extremely hard to find outfit. Many of the figural lights in the set are original, as they match the box art perfectly, as does the string. My search continues to find all of the proper figural lights to complete this set. I've seen only one other example of this outfit, and it was missing the lid to the box.

Monowatt, a major electrical device manufacturer, sold these lights under the name Cheer-I-Lights. A most unusual outfit,  this is one of the very few that I've found to originally offer pine cone shaped lamps from the factory. The set is presented in a very creative box that when folded turns into an attractive counter display using the inside flap pictured above. The lamps are German carbon filament exhaust tipped, and the outfit originally sold for $2.35. Notice the metal spring attachments on the sockets, used as an aid in positioning the lights upright on the tree. Monowatt made electrical devices, including plugs and lamp sockets for many years, but offered Christmas lights under their own name for only a very short time. 

About this time (1925), the industry started to use the "new style" GE ribbed cone lamps
instead of the smooth cones. The ribs added to the flame effect, and it was this final design that was made well into the 1960s as the preferred shape.

This Santalites outfit is one of the very few outfits that I've found that advertises a specific brand of Mazda lamps, in this case, Edison Mazda. The box does contain the specified Edison Mazda tungsten filament lamps.

Here is a set of imported German light reflectors, intended for use behind the electric light bulbs to enhance their brightness and sparkle. These were offered by Santalites, the same company who manufactured the light set pictured above. The reflectors are made out of thin copper with various colored coatings applied to the reflective surface. The inner ring is made of pressed cardboard, to electrically insulate the conductive copper reflector from the light socket.
