The journey began to replace 1 diagonal & add another diagonal. These dodgy LED strips from bang good already had a few LEDs fail, but all previous lights had dead LEDs since they were made. The decision was made to just burn test them.

These were rated for 12V.  They burn .7 - .8A at 11.5V. At 12V, the temperature rises rapidly & the brightness rises just a hair.

Adhesion of the squares, now $4 per pack, to plastic continues to be a problem.  This time, double sided tape was the attempt.

T pins are the new normal way to farsten the cables to the wall.

A .55R resistor dropped the 12V to 11.5.

It's exactly where the old one was for 5 years, but much brighter even at 11.5V.  The increased brightness might have a glare problem.   The LEDs are supposed to gradually fail.  They're slightly warmer but still a daylight white.
