Review on Outdoor Security Made Easy: 2-Pack Of DC 12V Low Voltage LED Flood Lights For Bright 6500K Daylight White Illumination by Peris Holland

I am so sick and tired of buying these Chinese LED's that claim to be D.C. devices, only to have them fail due to the internal A.C. Bucking unit inside. And some of my lighting is 17' up in the air, so changing them out is a real PITA. Now anyone who has bought outdoor LED lighting already knows that the wattage specs are Always suspect, and while these units are no exception, they will consume 20 watts, if given a higher voltage. At 12.01 volts D.C., they consume 1.334 Amps, which is about 16 watts. And that 16 watts puts out a hell of a lot of bright light.They'll start to fire at 7 volts, and draw 1.675 amps at 13.00 Volts D.C., which is about 21.77 watts. Heat always being the enemy, the 12 volt level will live longer. Also, these units are fairly liberal with the real estate. The LED units with the elements being placed contiguously, or like the 9 LED's potted together the size of a quarter, are the ones that always experience a premature failure. I have units here with 80 discrete (non-SMD) LED's still functioning now for 8 years.I'll be ordering some more of these units, but probably the 10 watt units, as these 20 watt units vastly exceeded my expectations. I'm off-grid here with a 3Kw 52Kwh PV system, so even the little lighting loads do add up. Highly recommended . 5 Stars.
