Question: How long have you owned this light?
Document: I used these to redo the lighting in front of my condo complex, and the board is very pleased. They do great in all weather (rain, snow) as long as they're in an outdoor rated flood lamp holder. Beam quality is great and plenty of light comes out (more so than the halogen par lamp it replaced), all while consuming hardly any energy. LEDs are the way of the future.
I replaced an old, burned out bulb outside with a CFL light. I was disappointed in the long warm up time for the CFL flood light to reach full brightness, so when the next bulb went out I decided to spend the extra money to get a LED replacement bulb. I am very happy with this light; it's similar brightness to the CFL in the socket beside it, but is full brightness as soon as it turns on.
Wanted an LED Par38 for an outdoor security light. I had a hard time paying close to 50 dollars per bulb but ended up buying a pair. Good color, they do look like incandescent light (even my wife admitted it and she's a  tough critic for energy efficient bulbs). Pretty good distance to the light (shine a long ways outside) but very spotty focused beam, that was my only negative besides the cost.
love the brightness of the lamp and savings that are promised but right now it will take a long time to recover $53 that the lamp cost and i need three others to boot. so I hope as time goes along the pricing will be more competitive.
I bought 4 of these and they seem really nice. They are pricey but I felt with a break even point of 2 years for my usage, it seemed worth it. You need to consider the long term savings and always increasing electricity rates.
Good heat sink design - ribbed metal body (fins) pulls heat away from the LEDs, which should help it achieve its long life. (heat causes LEDs to gradually lose lumen output over time). Weather-resistant design. Taking 1 star off because of the price. So far so good in outdoor flood usage. Note that LEDs are typically excellent in cold weather - they love cold (they hate heat). LED also means instant ON, unlike CFLs which need warm-up time.
These throw off a lot of light and did well above our garage to light up the driveway when we enter at night. Very happy with them.
We have two of these for street lighting on the side of our house. The light is white and pleasant. The bulbs work well with a timed switch.
They put out so much light that it spills into a larger area, but more on the edges of the circle, rather than even lighting. They do work, but the beam is more focused than I wanted.
These things just plain work. Instant on, use almost no power, and light up the driveway. If I had any sort of complaint it would be that the light is a tad harsh. Sort of like looking into the sun.
Answer: yes
