Using this lamp is easy. First, decide if you want to use it as a stationary or mobile light source. If you choose stationary, use the table clamp to secure it to a table. For mobile use, just roll it around on the rolling stand. Plug it into a 110v power outlet using the long power cord. When you need extra focused magnification, use the 8 - Diopter 1' circle in the lens. To maintain it, keep the lens clean with a soft cloth. Don't touch the LEDs with dirty hands as it may affect their lifespan. When not in use, fold it up to save space. And remember, since the LEDs last over 50,000 hours on average, you won't have to replace them often.
