Order Date: 2023-06-09, Received: 2023-06-22 The lamp is suitable for keychain size and weight. Not all of the specified technical data will be achieved. Fully charged, this lamp reached the brightness levels low-13.7 lux, medium-30.6 lux, high-90 lux, super bright-423 lux. At super bright, the lamp adjusts steadily after a short time and is only 70 lux bright after 5 minutes. After 115 minutes it is still 40 lux, after 128 minutes it is 10 lux and after 135 minutes it is less than 1 lux (a spot of moonlight). 40 lux. All brightnesses are measured at a distance of 1m. The lateral UV light has a color spectrum that is not suitable for checking bills. The battery capacity is only about 180 mAh. The charge is a little quick, which stresses the battery. But with rare use of the lamp this is certainly not a problem in terms of life.
Great, light weight, good access to turbo mode with a long press, the lumens do not know if they correspond but it gives very good light.
