1. LED lamps will flicker like ordinary incandescent lamps when driven by alternating current, but ordinary energy-saving lamps will not flicker. Strobe can easily fatigue the eyes.

2. The light of each LED bulb is too bright, which will strongly irritate the eyes, and it is not allowed to look directly, even for a short time, while ordinary energy-saving lamps are relatively softer!

3. The irradiation angle is limited, generally only 120° can be irradiated, while ordinary energy-saving lamps can almost irradiate 360°.

4. The brightness of the illuminated room is not better than that of energy-saving lamps, because LEDs only have high brightness in a narrow angle of direct viewing, and the light rapidly weakens after deviating from this angle.

Therefore, the advantages of LED energy-saving lamps as indoor lighting may not be more obvious than ordinary energy-saving lamps, but they are still very good when used as lamps such as torches, table lamps, and spotlights that only need to illuminate narrow angles.

The LED brightness (MCD) is different, and the price is different. LEDs used in LED lamps should meet the laser class I standard.
