Features: 1. It can provide all the light a plant needs to grow and bloom， making the plant grow faster and increase yield. 2. It's easy. High yields， low heat generation and less electricity. 3. Supplement light， especially during the winter months when daylight hours are short. . 4. Increase the length of the "day" to trigger specific growth and flowering to help plants grow faster and decrease the growth cycle. 5. Warm to the touch - will not burn the plant. No need for high power cooling systems， 50%-70% saving on energy cost Specifications: Item: SMD 5730 27 Full Spectrum LED Grow Light Power: 30W 40 LEDs (Replaces 300 Watt Halogen) LED Chips Total Power 30W=8 W (Actual Power Consumption) Voltage: AC85-265V 50 60Hz Material: Alunimium (Best Quality) Base Type: E27 (Universal Use) Beam Angle: 60-120 degrees Light Spectrum: Red: 630nm 660nm， Blue: 430nm 460nm， IR : 730nm， UV: 380nm， White: 6500K， Warm White: 3000K.
