materials:The MG infrared ruby glass red lights are made of hard glass and spiral tungsten filaments as the lamp core

advantages:

1. anti-explosion. hard glass material has low expansion coefficient，therefore even the light bulb is working and with high temp， It won't explode even if it accidentally touches water

2. fast heating rate. A 250W infrared bulb can increase the temperature by 4-6.4 degrees within six seconds. very suitable for cold weather.

3. energy saving. we adopt speacil technique to transform electricity into heat not light, so this infrared light bulb is very efficient and energy-saving 

4. long life service. it can be used at least for 5000hours 

infrared lights bulbs are widely uesed in poultry feeding, greenhouse planting, hotel food Heat preservation and moisture prevention，thermal therapy
