La description

Halogen tungsten lamp, also named Quartz lamp for whose bulb made by quartz glass。Actually, it develope basing on filament lamp, comparing with filament lamp, it is smaller, power is bigger, extremely expanded the application range and opened a new period for filament lamp. It divides into Bromine tungsten lamp and Iodine tungsten lamp from the material used。For the duration, Bromine tungsten lamp is not as good as Iodine tungsten lamp, but the irradiancy efficiency of bromine tungsten is better than iodine tungsten lamp (5% difference)。And it divides into tube and bulb as per their shape, respectively apply to different lamps. Halogen tungsten lamp with the speciality of small volume, big power, so working temperature is very high. The tungsten filament gradually vaporize, forming as tungsten steam moved to tube wall, creating halogenated tungsten with halogen by chemical combination in the low temperature place round tube wall, the halogenated tungsten has the high temperature migratory trend, bringing the tungsten back to the round of filament, and decomposing to tungsten and halogen again. This process called halogen and tungsten circulation, working to protect tungsten filament, thus, extending the duration of the lamp. Features： 1、Electric saving *0%~*0% comparing with common filament lamp； 2、Twice and above duration of filament lamp 3、Good light color (complete spectrum, it is best in all floodlights)； 4、Eyes protection； 5、No any pollution existed； 6、Unbeatable price（currently, it is the cheapest light source except the filament lamp） Parameter： Model No. Voltage(v) Power(w) Luminous flux(lm) Duration（h） G*5 **0 *8 **4 ***0 G**2 **0 *8 **4 ***0 G**4 **0 *2 **6 ***0 A**4 **0 *2 **6 ***0 A**7 **0 *0 **0 ***0 R**4 **0 *0 **6 ***0 R**2 **0 *8 **4 ***0 Equivalent contract with filament lamp： *8W=*5W *8W=*0W *2W=*0W *5W=**0W The light effect is ****0% more than filament lamp. The duration is ***0 hours，twice as filament lamp
