DC-DC 38V Digital Step-up Step-down Module Boost Buck Converter Solar Charging S
Excellent power supply
Very good as a bench power supply as long as demand is less than 5 amps, small footprint and decently high efficiency. Even running at a few amps the heat is barely noticeable.
9W 12W 15W LED Waterproof Spot Light Outdoor Garden Lawn Landscape Path Lamp
Good light, 12w not much brighter
I have both the 9W and 12W and there isn't a huge intensity difference between the two. The 12w is quite a bit larger - the 9W is plenty bright for landscape lighting and is small enough that it hides well.
