These things are like daylight. I do not think i would recommend for outside work lights unless the angle is pretty high. they are extremely bright. i have 4 of them mounted along the eve of my back yard roof line and you can see things in detail from about 120' away. it takes about 2-3seconds for them to spool up after you flip the switch. no weird power transformer required though. just std 3 wire. ground is required. no weird noise coming from them.
