It’s very clear that this light is actually based on a housing for a GU10 style holder and lamp. But to keep costs low they have basically fitted a round aluminium core PCB for the LEDs and the usual generic 3W driver in a bit if heatshrink.
The amount of waterproofing added to this light was annoying. It made it quite messy to take to bits and rules out any easy maintenance or repair.
The housing is not earthed, and has the loose earth wire and crimp lying loose inside. The LEDs are typical one watt bare luxeon style emitters soldered to the PCB and then reflectors with white housings have been glued over them.
I think I’d choose a version that takes a GU10 lamp and fit a standard 3W LED lamp into it. The slight downside to that being the possibility that the lamp may make poorer thermal connection with the outer housing than the PCB variant does.

Forty six years ago, Earth Day was founded by United States Senator Gaylord Nelson. Since then, pretty much all of the world’s environmental problems have gotten exponentially worse. Global warming, C02 levels in the atmosphere, the Great Pacific Garbage Patch and Donatella Versace’s face. But just think about how much worse it could have been. Sure people in Shanghai have to wear masks to breath, you can’t even bathe in the water from Flint, and Fukishima is spewing radioactive water into the Pacific Ocean. But at least the Polar ice caps haven’t all melted, covering the world in water and causing mutations that give us gills behind our ears.
Regardless of where you stand on the environment, you can still make money investing in companies that are going green or are eco-friendly. Maybe investing in green technologies like solar will help balance out your weekend hobbies that include pouring paint cans down the sewer, throwing batteries into bond fires, and chopping down the oldest trees you can find.
They may not be bad investments here either. For example, the Solar Industry ranks in the Top 12% of our Zacks Industry Rank. Jinkosolar is a Zacks Rank #1 (Strong Buy) while Solar City and Vivint Solar are both Zacks Rank #2 (Buy) stocks. For you vampires that hate anything related to the sun, take a look at Covanta, ticker CVA. Covanta is an owner and operator of large-scale Energy-from-Waste facilities. The company has an environmentally sound solution that generates clean, renewable energy from solid municipal waste. When life gives you lemons, make lemonade. I know what you’re thinking, this company is absolutely full of it. And you’d be right. The most recent analyst estimate revision for the current year comes in at 18 cents, well above our Zacks Consensus Estimate calling for 14 cents. It’s this recent upside revision and positive momentum in our Consensus numbers that have the stock clocking in with a Zacks Rank #2 (Buy). Analysts are looking for a 9 cent loss for the current quarter when Covanta reports after the market close on April 26th.
