===== LED Strip =====

I bought a LED Strip 10/30/2015 for the living room, which turned out quite bright, temporarily on loan to Nueva Vida, where it is not very bright.

^Part #20214|24-Volt High Output UL 16.4-Feet Flexible LED Strip with 600xSMD2835\\ 20214|
^Part #3258-24V|24 Volt 100 Watt UL Recognized Constant Voltage Power Supply|

The power supply would work intermittantly. Sent back to manfacturer for several weeks, they returned it, still failed intermittantly. Bought another from Amazon with a higher capacity. At Nueva Vida, the extension cord was faulty.
