These are not cheapest because they made to strict UL specifications with high quality brand name (not cheap generic) LEDs They emit 80% more light with color temperature similar to Direct Sunlight excellent color rendering index RA 90! This listing is for a 8 ft 2 inch long LED light strip with 150 pieces of 120 degree light dispersion angle 3528 SMD. Strip contain 150 Pure Neutral / Pure White (color temperature 5000K) LEDs. Power consumption under 12 watt (12 volt 1 amp DC) light output 800 lumen equal to 75 watt incandescent light bulb! These strips are made as flexible printed copper circuit boards less than 3/8" wide and only 1/8" thick with 3M self adhesive back. Strip can be cut every 1 -7/8" (3 LEDs) each part can be soldered and powered by the same or additional 12 volt power supply. LEDs spaced less than 5/8" apart, 19 LEDs per ft. Extremely easy to install. Photo below shows an example of kitchen installation - strip was cut in 3 parts, 3 holes of 1/4" were drilled, wires and power supply are hidden in cabinets. About 12 ft Bright white strip is used in this installation. These strips are perfect for kitchen under cabinet lighting, glass door cabinet lighting, accent, picture and decorative lighting, produce brilliant white light! The light output is equal to 3 x 20 watt halogen bulbs. Please do not confuse with low power strips: these are very bright LEDs and you'll need 12 volt regulated power supply capable of at least 1 Amp (1000 mA) output. Strip shipped with Black (negative) and Red (positive) wire leads. 12v 1.5a power supply can be provided for $9.99. The expected life span is more than 50,000 hours. Our current model made on strong white 2oz copper PCB (most sold by others made with thin 0.5oz copper PCB) Thanks for reading!
