Antique Bulb Discussion / New Book on Incandescent Lamp History
« Last post by James on November 24, 2021, 09:17:10 am »
A new book 'Rays of Light' is about to be published by Ray Tye, one of the premier collectors of early incandescent lamps. I have had the great pleasure of knowing Ray for over 25 years, and the chance to study his world-class collection on several occasions. His career as an archivist provided unique access to a wealth of vintage materials, and an impeccable research methodology which is demonstrated by his deep knowledge of the technical, commercial and personal aspects behind the development of early incandescent light sources.

Retirement has provided the opportunity to document his vast knowledge, distilled into a 504-page hardback tome accompanied by 300 photographs and 118 illustrations. I have always admired Ray's fearless attitude to light his lamps, and this photographic record promises to present these artefacts in a way few of us are likely to have ever seen. Interlaced with stories of competition of the incandescent lamp with gaslight and developments in arc lighting, this would be a superb introduction for anyone interested in the history of the electric light - as well as a professional reference work to aid other enthusiasts.

A limited print run will take place in the next few weeks, and the cost is likely to be around GB £30-35. Ray is not interested in making a profit from his life's work, but would like to see it reach a wide audience of fellow lighting enthusiasts. His printers will send directly to anyone around the world for the cost of the postage.

If you wish to acquire one of these remarkable books, please reply to this thread and/or send a message with your name/address and I will pass this on to Ray. Do not delay, he needs to know ASAP what quantity to order at the printers!

Modern Electric Lighting / Micro incandescent lamp
« Last post by Yulelights76 on November 07, 2021, 11:01:54 am »
This is the smallest incandescent bulb from my collection. I don't know if it is the smallest ever made.
It is a micro bulb used to backlight the LCD display in a budget wristwatch. The bulb measures 1/16 inch (1.5 mm) in diameter by 1/8 inch (3 mm) long. not including the wires. It dates to 1989. Watches from that era also used red 7 segment LED displays.
The lamp draws 12 milliamps current at 1.5 volts.
I have grain of wheat bulbs, but this one is much smaller. Does anyone else have any bulbs like this or smaller? :?

Modern Electric Lighting / New type of metal halide lamp.
« Last post by adam2 on October 09, 2021, 11:06:00 am »
New to me at any rate.
A double ended metal halide lamp that contains TWO discharge bulbs, connected in series.

Presumably intended for use with a series magnetic ballast on 380/400/415 volt circuits, or an electronic ballast.

The first piece posted is not a light bulb, but a lightning arrestor.

Marionhuff, is your piece the same or a different type? You can email me pics directly (cmshapiro@me.com) if you canít upload a pic here and I can probably help you ID whatever you have.

Antique Bulb Discussion / Thomson Houston Base
« Last post by Alexander on April 07, 2021, 03:28:58 am »
Hello to you all,
I have a thomson houston socketed shelby Lamp. I want to build a lampholder for it. Therefor I need the thread type that is needed for the centre bolt. I live in France so I donut have access to american style bolts, to check it out myself by trying out, as I have to order the bolts from special marketplaces outside.




Best regards

Alexander
