Drawing:
Two-hole tube strip-shaped light device is a highly effective semi-conductor light device (Gekko two-hole tube), which includes one series of large-screen bombers, and one containing 10-20 narrow strips of light columns (see picture 1). This usually includes 20 to 50 shots, and each shot has 100 fine grains. Typical commercial equipment has a long duration of 100 meters, an output rate of 10 meters, and a very high success rate of ≈200 tiles; lifespan ). In the past 20 years, the specific price of each tile has fallen, and the quantity level has also increased significantly at the same time.
