Without the resistor the LED would run at too high of a voltage, resulting in too much current being drawn which in turn would instantly burn the LED, and likely also the GPIO port on the Raspberry Pi. The XLamp XP-G3 S Line LED is built to hold up to twice the number of switching cycles of other LEDs in the same class. Also, in contrast to traditional technologies, LEDs turn on at full bri… Or maybe the circuit board, which has a backlit LCD display, consumed a significant amount of voltage and now, with it removed, the lights were getting too much? Knowing the importance of light cycles for cannabis before even making your first move is as important as looking for the perfect growing soil for your plants. Recently it started cycling off and on while attempting to heat my spa. Outdoor marijuana plants in the wild (or those grown by marijuana growers) generally enter their flowering stage towards the end of the summer season and continue flowering throughout the end of the fall season. over current) kicking in on the power supply. For the white you could try a Mean Well LDB-300L 40V boost driver ($5.85 at TRC). Now, to be fair, I have to note that turning bulbs on and off more often can shorten the life of the bulb itself. The LEDs are likely wired 3 series LEDs in parallel 3S3P and 3S4P so there would need to be more than 2 current limiting resistors. Check the VCC voltage, and then voltage on the track between the 7805 (U5) and C3, it should be 5V. I purchased and installed a new 100-watt high-pressure sodium lamp (and left the new sensor in) and it was like a new light โฆ Or about 9V across either or both.
