I bought this lamp because a reviews of youtubers Nutnfancy and it has exceeded all expectations. The lamp is in the lowest brightness extremely long (and that is really light) and acting in the highest brightness like a searchlight. There is a function for "SOS" sign as a signal transmitter and my favorite: Strobo! The rest is so bright and disgusting effective that you may not daily 2 seconds to do nothing more sees itself in a lighted room. Perfect for threatening situations at night (if you ne hard right, without which acts the au nothing.)
