Heat Shrink Tube is available in different sizes and thicknesses to accommodate different wire or cable diameters. It is often used to insulate and protect electrical connections, providing a barrier against moisture, chemicals, and physical damage. The shrink tube can also be used to bundle wires together, providing organization and strain relief.
In addition to insulation and protection, heat shrink tube can also be used for identification purposes. It is available in various colors, and can be printed or labeled with text or symbols to indicate wire or cable identification, circuit identification, or other information.
The application of heat to the shrink tube causes it to shrink and conform tightly to the underlying wire or cable. This can be done using a heat gun, oven, or other heating methods. The heat causes the polymer material to melt and flow, resulting in a tight and secure fit around the object.
Overall, heat shrink tube is a versatile and reliable solution for insulation, protection, and identification needs. It provides a durable and professional finish to wire and cable connections, ensuring long-lasting performance and safety.

Unlike other Hue family products, Hue Beyond builds two sets of light bulbs, each of which can be independently adjusted to apply lighting to different scenes. 
As shown in the figure of Hue Beyond intelligent luminaire, it consists of two bowl-shaped hoods, the upper part is made of aluminum metal and the bottom is made of glass. The lamp set provides a total brightness of 1200 lumens and a service life of 15,000 hours.
In daily use, there are a set of light bulbs in each of the two covers, which can respectively produce different atmospheres of illumination. For example, during daily reading, you can adjust the lower part of the light bulb to produce white illumination for reading, while the upper part of the light can be adjusted to color to change the background atmosphere of the room. In addition, the user can use a certain color of the luminaire as a reminder that the luminaire supports the IFTTT conditional triggered notification service to generate different colors to alert.
The dome and chandelier versions of Hue Beyond are priced at €530/£500, while the table lamp-style Hue Beyond is priced at €330/£300; it is now available in the UK and continental Europe. There is currently no sales time and price information for this product in the US.
