I installed four of these 12 volt spotlights to uplight the front of our house. The shadowing looks great; It adds a bit of drama to the overall lighting.
The lights' bodies are metal construction and feel rugged. The glass lens assembly screws on, with a rubber O-ring for a water resistant fit.
The ground stake is made of plastic, which is obviously a cost saving thing. Not thrilled about the plastic, but the low price makes up for it.
I prefer 2700K color lighting, so I swapped out the included 3000K bulbs. The color hue difference is subtle, but since MR16 LED bulbs don't cost much I decided to do it. I paid $19 on Amazon for box of six 4W 2700K bulbs.
Don't forget that you will need a 12V AC or DC landscape lighting transformer to power these "low voltage" lights. The included lamps are rated 4-watts (12 Volts @ 0.33 Amps each), so pick a transformer that will handle the combined wattage of ALL your lights, plus at least 25% extra wattage to prevent overloads.
Lastly, I used 12AWG and 14AWG landscape lighting wire and buried it at least 8 inches deep. Both are heavy gauge wire that avoids voltage drop on long runs. And their thick insulation protects against minor garden shovel accidents when planting flowers, Low cost, metal construction, simple installation, replaceable MR16 style LED bulb.
