Full Spectrum: These LED grow lights feature 24 5W 4000K warm white LEDs, providing a true full spectrum with a wavelength range of 380nm to 780nm. They replace sunlight and provide an optimal spectrum to meet plant growth needs, helping them grow healthier. They are ideal for all growth , including indoor plants, seedlings, vegetables, and flowers. Energy-Efficient: These full-spectrum LED grow lights utilize high-performance Bridgelux LED chips. Each LED reaches a maximum power of 5W. With actual power consumption of only approximately 35 , they can replace traditional 100W high-pressure sodium lamps for even greater energy savings. Equipped with a 60-degree lens, these bulbs achieve PAR/PPFD performance of up to 2200umol/m²/s at 8 inches (approximately 8 cm), PPFD performance of up to 1040umol/m²/s at 12 inches (approximately 104 cm), and PPFD performance of up to 450umol/m²/s at 18 inches (approximately 45 cm). Excellent Heat Dissipation: and compact, yet delivering ample light and excellent heat dissipation. The LED bulb features a built-in heat sink and fan, ensuring excellent heat dissipation and a long lifespan. The fan utilizes dual ball bearings, superior quality to oil-filled bearings, and is exceptionally quiet, with a maximum noise level of only 30 decibels. Wide Application: The white grow light is similar to a standard light bulb with a standard E27 socket. It can be widely used in various plant growing environments, such as nursery tents and nurseries, to quickly improve plant health and growth. Coverage Area: The grow light covers an area of ​​up to approximately 4.20 square feet (18 to 28 inches) above the plants, and the lighting duration varies depending on the plant (up to 10 to 12 hours).
