Characteristics of explosion-proof metal halide lamp

Sc-Na is 120 lumens/watt (lm/w).

Dy-Tl is 83 lumens per watt (lm/w).

2. Excellent color, because of the continuous spectrum, you can get comfortable light.

3. Life and beam retention are worse than other HID lamps.

4. The starting and restarting time is longer than that of other HID lamps, which is easily affected by the change of power supply voltage.

The starting voltage is high, so special ballast is needed. However, in Sc-Na system and Na-Tl-In system (low starting voltage type), the starting element is attached to the bulb and is equipped with mercury lamp ballast (blocking coil method, leakage transformer method, etc.). ) is used.
