The lamp is mechanically stable, the assembly and mounting well explained and easy. The light is on power right there, does not flicker and spreads very well on the work surface. After bad experiences with a light from the hardware store, but it was cheaper 17 virtually useless, I would buy if required immediately, the Philips lamp. A star deduction only for an organizational problem of the supplier, the delivery was delayed by one week (was probably a one-time problem, so bad luck).
