Our main customers are contractors and wholesalers. Usually it is OEM service. If you want to know about our OEM service, please contact us directly.
At present, we have produced 7 kinds of spotlights that are ubiquitous in the market for many contractors, Their difference lies in the size and shape, and the way of adjust the shroud.
Our spot light is one of the landscape lighting industry's most liked solid brass fixtures and is best choice for any uplighting application. There is no powder coating, paint or finish to wear off or peel - just the natural beauty of solid brass that patinas.

Pump cavity by a pair of leaf-shaped rotor synchronous, reverse rotation of the push to move the gas to achieve vacuum pump. Its structure and working principle is similar to the Roots blower. When working, the suction port of the vacuum pump is connected with the main pump of the vacuum pump or the vacuum system. The rotor and the rotor of the vacuum pump are not in contact with each other between the rotor and the pump casing, The gap is generally 0.1 to 0.8 mm; do not need oil lubrication Rotor-type lines arc, involute and cycloid involute rotor pump volume utilization is high, the processing accuracy is easy to guarantee, so the rotor-type lines and more gradually Open line. Roots vacuum pump speed can be as high as 3450 ~ 4100 rev / min; pumping rate of 30 to 10,000 liters / second (1 liter = 10 (m; limit vacuum: single-stage 6.5 × 10 × 10 (Pa. Roots vacuum pump is characterized by: fast start, less power consumption, low operation and maintenance costs, is pumping gas containing a small amount of water vapor and dust insensitive to 100-1Pa pressure range high pumping rate, can quickly exclude sudden release of gas. the pressure range is just mechanical seal between the pump and diffusion pump. Thus, it is often connected in series between the diffusion pump and mechanical seal vacuum pump, to increase the intermediate pressure Range of pumping volume. At this time it is also known as mechanical booster pump. Roots vacuum pump is widely used in vacuum metallurgy smelting, degassing, rolling, and chemical, food, pharmaceutical vacuum distillation, vacuum concentration and vacuum Dry and so on.
