This plant lamp can promote plant growth, it can apply to all plants grown in soil or hydroponics. Suitable for any growing process. Equipped with high quality 18LEDs (12 red and 6 blue) and E14 base, it can be substituted 3-5 times the power of high pressure sodium lamp, except 80% energy than lamps traditional high pressure sodium and metal halide.High efficiency light: 90% of the emitted light can be absorbed by aquatic plants. But the traditional high pressure sodium and metal halide lamps has only 8% -10% of the absorbability. Aluminum material, this lamp has no toxic, no lead or mercury. Integrated cooling system, it has good thermal dispersion. You can use it for 50,000 hours.Lighting space: 2-4m?. It is best to light your plants for 10-16 hours at the plant height of about 30 cm. Features: Dimension: Diameter 48mm, Height 65mm Material: aluminum Weight: 40g Voltage: 85V-265V Power: 8W Luminous flux: 635-735LM Attention: Use only in indoor space or greenhouse because the bulb is not waterproof. Do not put the bulb in water or there will be a risk of electricity leakage. The plant lamp works in normal condition, -20-40 ? temperature, 45% -95% relative humidity.
