Issues with Poultry House LED Lamps and Light Dimmers LED lamps have changed the landscape for poultry growers in terms of energy savings related to poultry house lighting. No other lighting source (incandescent, compact fluorescent, cold cathode, high pressure sodium, etc.) comes close to the energy efficiency of LEDs. LEDs are roughly 80–85 percent more efficient than incandescent lamps. However, during the transition from incandescent to LEDs, there have been some hiccups (Tabler et al., 2019). Starting late last fall, we began getting an increase in calls from growers concerning strange dimming issues and premature LED lamp failures. Trips to various poultry supply vendors and LED distributors revealed boxes and boxes of failed LED lamps (still under warranty) of various brands that had been returned by growers. Through conversations with these vendors and distributors, we determined that the premature lamp failure problem had been steadily increasing in recent months. This is not normal nor expected, and it led us to dig a little deeper into what was going on. While we haven’t solved all the problems, we now better understand much of what is causing premature LED lamp failures and why some LEDs are losing brightness much more quickly than expected. Like many other complicated issues, it is not just one thing causing these problems. Apart of the issue is the lamps, a part is the light dimmer, and a part is the compatibility between the lamps and the dimmer. Figure 1.
