Recently, I tested a large 100W CoB rated for 12V, advertised to draw 8-9 amps. Despite its size and claims, my measurements show it only reaches 30W at best. If you multiply the voltage and Read More
LED lamp brightness should be tested with specific instruments that measure light intensity in lumens and power consumption with a watt meter. Dividing these two yields a value known as lumens per watt (Lm/W), Read More
