Cost of a Grow Light comes down to several other factors that need to be considered before making the purchase, for instance,
Size of Grow Light
- Is it a small fixture that draws fewer watts or a large fixture that uses more power?
More power is generally associated with a more expensive grow light. Additionally does the diode, brand and bin.
Top End High Quality Led’s
- Does the unit use industry-leading top end LEDs?
Top end higher quality diodes will be more expensive.
adding secondary optics increases light intensity and may add an additional cost to the fixture.
Do you need secondary optics for your grow space?
Are the heat sinks large?
Does a unit use efficient top brand drivers?
Are the fans rated for 50,000 hours or more?
If, yes, this will increase the price of the fixture PPF?
Does a fixture emit a lot of light?.
more light equals a larger investment
Are the diodes and the fixture efficient
Is there a high ratio of light per Joule of energy generally above 1.5 micro moles per Joule is considered very good.
The top fixtures are currently rated at about 2.3 micromoles per Joule.
Higher efficiency equals more expensive LED grow lights.
Coverage-Area (Foot Print)
Does the fixture cover a :
2′ x 2′ footprint
3′ x 3′
4′ by 4′
or more larger fixtures that cover more area are more expensive as they possess more and more advanced features.
