Airam-candelabra

Airam-candelabra

This is probably about the last Christmas light made in Finland. Here is Airam's specialty, the power splitting diode. That's why it uses 7x 20V bulbs with 230V mains.

Some years ago I didn't found the correct spare bulbs, so I installed these LED bulbs. I had to remove the power splitting diode too.

Very nice! Love seven armed fixtures. I dont like the LED replacement bulbs much, they dont cast the light in the same way incandescents do.

I like it. Would look great with seven flicker flame neon lamps.

Thanks.

Original spare bulbs are in principle available: https://www.airam.fi/en/product/v5883-2402/4719248/spare-bulb-pikyp-3w-20v-e10-clear/159/1 The problem is you should find a dealer.

Apparently some flicker flame lamps are also available: https://www.airam.fi/en/product/v5883-4077/9477329/spare-bulb-3w-34v-pik-e10-flame-7pc/159/1 I don't know if they fit this candelabra.

20V seems a little low for a fixture like this, it give you a lot of light but wont last long!
Series 7-arm fixtures like these used on 230V use 34V bulbs. They are readily available in Sweden, you should take the Finslandsfärja over here and get some.

Yes, a basic 7-arm fixture uses 34V bulbs. These Airam sets use the power splitting diode, that's why 20V is correct voltage for bulbs. The disadvantage is the vibration of the light.

There are these retrofit bulbs: https://www.lighting-gallery.net/gallery/displayimage.php?album=5228&pos=1&pid=169762

That is really odd, and cool. Some kind of power saving idea?

It's hard to say what the reason was. Maybe there was a desire to avoid the need for many kinds of bulbs. I do not know that other manufacturers would have the same solution.
