Power:70W,150W Color Temperature:3000K/6000k High Efficiency and energy saving, luminescence efficiency 90-120 Lm / W. Anti - ultraviolet, high color display, Ra> 90 Longer life expectancy, average life expectancy of up to 30,000 hours Color temperature drift of small, photoelectric good consistency Two ends electrode silvering processing, in order to maintain a lamp and the lamp more good contact, and electricity supply wires from ceramic packages, can prevent high temperature oxidation The level of mercury in products lower than other gas in the discharge light source, it? an environmentally friendly products.
