  • No lead or mercury means easy and environmentally safe disposal
Description

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.

Energy Used

A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
 
Energy Used
16 Watts

Incandescent/Halogen Equivalent

The wattage value of an incandescent or halogen lamp of similar brightness.
 
Incandescent/Halogen Equivalent
75 Watts

Volts

A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.
 
Volts
120

Base

The end (or ends) of the lamp that fits into the socket.
 
Base
Medium (E26)

Bulb Shape

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".
 
Bulb Shape
PAR-38

Bulb Color

The color of the light produced by a bulb
 
Bulb Color
White

Brightness (Lumens)

A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
 
Brightness (Lumens)
670

Bulb Finish

The surface finish of a bulb, which may affect the quality of the light emitted.
 
Bulb Finish
Clear

Bulb Technology

The technology implemented by the bulb, e.g. incandescent, halogen, LED

LED

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
 
Average Rated Life (hr)
50000

Operating Temperature (°F)

The ambient temperature in which the product can safely operate.
 
Operating Temperature (°F)
-4 to 104

Beam Angle (°)

The width of a light beam, expressed in degrees. The beam angle is often part of the ordering code for reflector lamps. For example, a 50PAR30/HIR/NFL25 is a 50-watt PAR30 narrow flood lamp with a beam angle of 25 degrees.
 
Beam Angle (°)
60

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
 
Length (in)
5

Diameter (in)

Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
 
Diameter (in)
4.7

Housing

Thermal Plastic

Warranty

5 years limited

Wet Location

Suitable for exterior or interior location in which uncontrolled liquid may drip, splash or flow on or against electrical equipment.
