Better energy-saving advantage: more than 2.5 times the energy-saving of the current blackboard lamps on the market.
① Compared with the market standard products, the overall light efficiency is 70Lm/w, which is more than 40% energy-saving (our company is 98-125Lm/w).
② Compared with the market standard products, the overall power is 3*36w=108w, which is more than 251% energy-saving (our company is 21.5w*2=43w).
2) The dimming method is more humane: 77%-100% two lighting modes, which can achieve 500Lx-950Lx illumination selection.
3) Longer life: The lamp body basically does not heat up, reducing the light decay speed of the light source, thereby extending the service life of the product.
4) Beautiful, neat, and firm, avoiding the swing of the lamp back and forth.
5) Avoid glare: When the blackboard lamp is illuminated, the face of the person is perpendicular to the blackboard surface. When the person stands at a parallel distance of 650mm from the blackboard surface and looks up at the blackboard lamp, the light source and the light-transmitting lampshade of the blackboard lamp cannot be seen
