Optimize Testing

摘要

My sister watched as our friend Bob, an experienced electrician, installed a ceiling fan in the mudroom at our dad's house. "BLEEP poor design on the fan," she texted me. "It took him forever to install." When it came time to buy another ceiling fixture-this time a heat lamp-I decided to search online. I found a promising one and looked at the reviews. According to one buyer, though, the unit allowed insufficient space between the heat plate and the cap. That flaw caused a lack of airflow, which triggered the unit to overheat just after a few minutes of operation.
