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.

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

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

One or more of our member on this site could date this bulb

Pretty, please no more Chinese failure.

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.
