Lighting Science VividGro 75 Watt Equivalent, 16 Watt, 120 Volt LED PAR38 Grow Bulb

Lighting Science Group PAR38 16 watt flood LED grow bulb generates as much light as many 75 watt halogen bulbs. The grow bulb is an energy efficient and spectrally optimized lighting solution for a variety of horticultural lighting applications, including homeowner/hobbyist, greenhouse and growth chamber. The bulb optimizes delivered photosynthetically active radiation (PAR) to maximize plant growth and PAR efficacy while providing white light suitable for the human visual system and excellent color saturation.

• Excellent PAR output and photosynthetic efficiency
• Spectrum tailored to maximize photosynthetic absorption
• No radiated heat to allow for maximum irradiance at close proximity to plant canopy
• PAR38 lamp design is ideal for small grow areas
• One lamp is suitable for a 1 square foot area of plant canopy
• Passive cooling, no fans or moving parts
• PAR Output:  20.58 µmol/s
• 40° optical distribution allows for more moderate light levels for most indoor plant applications
• Spectrum contains 16% blue (400-500nm) to support strong stems and compact growth
• Very long life - Rated to still put out 70% as much light after 50,000 hours of operation as it does when brand new

Not recommended for use in fully enclosed fixtures because heat buildup will shorten life. Do not “hot swap” this bulb. Turn off fixture before replacing existing bulb.
