These can be purchased at most big box stores for around $20 a piece. They are a standard 4’ long. These make an excellent trial light when you are ready to try growing indoors or need to go with a vertical rack to increase growing capacity in a limited footprint.
Pros: Inexpensive, easy to find, acceptable light spectrum 2200k-4000k for microgreen growth, produces minimal heat, can usually be daisy chained 3-4 lights, works with 120v household electrical outlets.
Cons: Bulbs are often unprotected from water and dust making them susceptible to damage, brands vary greatly in quality, normally designed to be installed horizontally only, less efficient than strip LEDs, generally last far fewer hours than strip lights, light spectrum too low for longer growing crops (this shows as discoloration in the leaves in later stages of growth or plants becoming too leggy and falling over before harvest).
All of that being said, I have been using the original 5 of these that I started out with in my growing room for 2 years now. They work fine for the shorter growing cycle crops but I found that micro herbs and longer growing cycle crops needed the higher light spectrum available in the LED Strip Grow Lights to reach potential.
