Halogen Lamps (R Series) are upgraded version of incandescent bulb, which are also known as tungsten halogen bulb and quartz bulb. Halogen added bromine and iodine to protect tungsten, as well as having much high efficiency compare to incandescent. On average, halogen bulb saves up to 30% of energy compare to incandescent bulb. Halogen bulb are available in a range of bulb shape and power rating. For bulb shape, the most common models are R50 | R63 and R80. They are also called reflector bulb over the world and are wildly use in clinical fixture lighting. The halogen R series bulb have power rating ranging from 18W to 70W, which the total lumen is within 200-850lm. Both Series can be seen in small Edison screw bases such as E12 | E14 as well as, larger Edison screw such as E26 | E27. Bayonet bases such as B15d and B22d are also available.
Halogen bulb usually have a color temperature of 3000K, which could have a slight variation between 2700K-3100K). The light source has a very good color rending which CRI could be as high as 99, which almost restore coloring of sunlight. If you wish to have a strong light bulb, we recommended to use clear bulb shell with highest light transmittance. If more diffused light source is preferred, we recommended a frosted glass cover or an opal bulb shell which give our more diffused light. The lighting effect of halogen bulb is very attractive to Europe (especially U.K.), North America, Latin America as well as Middle East market for general lighting purpose. It is particular safe and reliable, as well as being the most commonly used indoor lighting product. The product fully complied with CE requirement. Which the product life time is around 2,000 hours.
