Power Twist fluorescent light

Click to view full size image

True Lite. Power Twist. Duro Test.
Nice cool tube light, don't know anymore where I found it but it still works. No kathode shield and daylight colour.
Why did they make this kind of tube lights?
I don't know what year it's made.

The twist is done because its supposed to give extra brightness.

Its All For The Christmas Lights...

The twists gave the glass additional surface area, thereby increasing lumens per watt, something often compromised on deluxe halo phosphate daylight lamps.

Duro-Test made some fine lamps and the utilities used them for their incandescent street lights.

We had these in UK for lighting aquariums, they were said to give out some UV, could be 1970s as I at the time lived SW20 Wimbledon, never see them now. Yes the twist gave more surface area so they claimed. These tubes were fairly heavy.

Interested in the history of electric lighting and incandescent in particular and neon glow lamps.

Power - Twists were common in Switzerland in the 1970/80s. My former neighbor which is a painting artist still uses them in his atelier as work lights.

These tubes cost about three times more than a regular DE LUXE tube of the same wattage and were imported by a trader called Renesco.
