According to the National Development and Reform Commission, the roadmap for incandescent lamps will be phased out. Starting from October 1 this year, the import and sale of ordinary lighting incandescent bulbs of 60 watts or more will be banned. Recently, reporters visited the Zhongshan market and learned that some crystal lamps are still in use because of the good luster effect of incandescent lamps. Because of their low price, some workers at the construction site still use their lighting. The market can still buy more than 60 watts of incandescent lamps recently. The reporter visited 10 lighting shops in Gongchen Road and found that there are still 7 stores that sell more than 60 watts of incandescent light bulbs. However, the store said that sales have been small. There are very few customers who buy incandescent bulbs separately, but because the gloss effect is better than LED lights, the proportion of crystal lamp ornaments and chandeliers using incandescent bulbs is still very high. The staff of a lighting store in Gongchen Road said. The staff of another lighting store said that incandescent light bulbs are now less popular, and it is normal to not sell an incandescent light bulb a month. The highest-power incandescent lamps currently sold in the store are 60 watts and the minimum is 25 watts. She said that incandescent lamps consume electricity and have a short life span. They are already eliminated products. We introduce more LED lights to customers. Since last year, China has banned the sale of incandescent lamps of more than 100 watts, but the reporter also found 200 watts of incandescent lamps in a hardware store in the Eastern District. According to the owner, the bulbs are cheap, many people buy lighting when they are renovating, and some building sites use 200 watts of incandescent bulbs. The use of LED lights and energy-saving lamps into the mainstream reporters noticed that almost all the lamps on the shelves of the lighting stores are LED lights and energy-saving lamps, incandescent lights are only asked when the clerk will come out. In a well-known brand of lighting stores, the staff said that LED lights and energy-saving lamps have become the mainstream of the market, incandescent lamps are currently not stocked in the store. Incandescent lamps consume a lot of power and are easy to break. If you count them, you can still use energy-saving lamps, so many users tend to use energy-saving lamps or LED lights. The staff said. Before the National Development and Reform Commission announced the roadmap for the phase-out of incandescent lamps, Guangdong Province has promoted efficient lighting products. Zhongshan City launched the promotion of financial subsidies for high-efficiency lighting products in 2009. According to the statistics of the Municipal Economic and Information Bureau, from 2009 to 2012, the city promoted a total of 1,89,372,000 high-efficiency lighting products, exceeding the promotion tasks of the province.
A Top Sub, or Crossover Sub as it is sometimes called, is used to attach the motor to the drill-string.
The crossover Sub typically has a standard API box connection that connects to the drill-string and a proprietary pin connection that connects to the motor.
Top subs may also be designed with a float bore for those applications that may require Float Valve.
Optionally, a dump valve sub can be used in place of the top sub.
The dump valve sub has the same function as a top sub, but instead contains an internal bypass valve that enables the fluid in the drill-string to drain out when the string is pulled out of the hole.
