1, portable halogen spotlights use halogen bulbs with high color temperature and high light efficiency, which are actually incandescent bulbs. Adding halogen can prolong the life of the bulb, the illumination range can reach 200-300m, but the power consumption is large, generally around 20W;
2. Portable LED spotlights use multiple LED bulbs. Led is a cold light source with high luminous efficiency, low power consumption and long service life, but its range is not as far as halogen lamp, so it is suitable for short-distance lighting.
