I use it when camping and as a passenger while driving. Stage 2 I use when embroidering, because that the light must be very bright. The lamp can be this conveniently attach the hoop! The flexible lamp neck, the light beam can be aligned to match! The clip at the lower end is opened by firm finger pressure. He seated properly and does not come off easily. Here everything is right and is totally functional. I was skeptical at first whether such a small lamp can really generate enough light - but this part has absolutely convinced me. Meanwhile, I have a lamp firmly deposited in the car and a caravan. This is a strong buy recommendation!
