- This video explains the differences between the vintage Christmas light bulbs sold by TheOneStopSatShop and buymystuff.co.uk
It is important to select the correct voltage and thread size that you need. The particular light bulbs in question are used in 12 and 20 light vintage sets made by Lyvia, Dencon, Pifco, Woolworths and many more.
Also featured is the candlebridge bulb, an E10 34V version which is used in many 7 set welcome lamp units.

i had forgot that battery test thanks for the information great video❤❤
brilliant bit of film, very useful.
I ordered some of these UK bulbs (maybe from you!) several years ago here in the USA, and want to make some series-wired sets. The bigger bulb is the same as our "C-7" or "C-7-1/2" size bulbs, but our sets are wired in multiple (parallel) and use 120 volt bulbs independent of each other so a failed bulb or loose or broken bulb can't cause an outage of the entire set. The drawbacks are that 120 volts is across each bulb so a broken bulb is a serious shock hazard (although it would also be on a series set actually) and the wattage is cumulative because you multiply each bulb's watts by the number of sockets, for example, 10 sockets with 7 watt bulbs is 70 watts, or 50 watts with 5-watt bulbs. These series-type 12 volt bulbs at 3 watts each, running 10 in series on our 120 volts, won't be a total 30 watts, or 10x3, but will end up a bit lower, because of the series wiring and that all 10 bulbs in series act like one big bulb with a 120 volt filament than 10 bulbs with separate filaments, which makes the resistance lower and the watts higher than series. I am a Christmas light collector and enthusiast, and these UK lights have real merit for me. I can make up the E-12 sets in series easily, using parts from old sets. I also can get the E-10 sockets--those were out older type "C-6 series" type lights, with 8-15 volt, 4.8 watt bulbs in series. The reason for the 4.8 watt filaments, is that they used the same size tungsten wire as 40 watt GLS bulbs! In fact, I use a small sized 40 watt bulb in my 120 volt bulb tester to test 15 volt C-6 bulbs directly on 120 volts--the 40 watt bulb basically acts as the "other 7" bulbs in an 8-light set, and the C-6 runs just a trite below the brightness it does in a regular 8 light set. I also use the "9 volt battery trick" on our 15 volt C-6 lamps. I have some of each type of bulb shown here, and will make up sets for them. I also have a vintage boxed British Philips 12 light set that takes the translucent ("opaque") 20-volt bulbs. These are cool bulbs and unusual in the USA. The only issue is with the E-12 bulbs--if they go in a regular parallel C-7 set, it'll blow the bulb to kingdom-come! So care where care is due! Cheers! Rick "C-6" Delair.
Hi Rick. Interesting comments from yourself and you clearly have good electrical knowledge. What you are saying is basically all correct. The bulbs in question can be used on any line voltage provided you correctly calculate the volt drop across each bulb. For example in a 120V system you can use 10 of our 12V lamps in series. It is advisable not to mix the types used as the resistance of the lamps can be a little different which can induce a small voltage imbalance. A lamp operating with 13V across it will have a shorter life. Being permanent contact lamps they are unfortunately unsuitable for parallel operation directly.
Well done! Thank you.
Many thanks for your support.
I am guessing there are no parallel connected sets available in the UK as you would need 240V bulbs.
Parallel sets are less common and tend to be used in ornaments but they would still be low voltage and use a separate mains transformer.
Do you have any tips on repainting bulbs that have been faded or chipped? Like type of paint to use, and how to make it stick?
Moon Hitsearth Hi, sorry not too sure on the paint used but many customners touch up damaged areas of the lamps with felt pens or marker pens.

I appreciate your reply, but I think I'm beyond markers, On some of them it's half the bulb, from sitting in the sun, thank you again.
Do you have any of the elusive 7.2v midget base christmas bulbs for sale?
