Grow light bulbs, strips or fixtures?
Indoor plants can get their light from a bulb in a lamp you already own, a strip under a shelf, or a fixture hung over a tray. All Zone grow lights are full spectrum, red and blue. What changes is how the light is mounted and how much area it reaches.
Which kind for which setup
| Kind | Fits | Zone grow lights |
|---|---|---|
| Grow light bulb | A lamp, clamp light or ceiling fixture with a standard E26 socket, for one or a few plants | 4 |
| Grow strip | Under a shelf or along a plant rack, over seed trays in a row | 2 |
| Fixture | Hung or clamped over a bench, a tray or a group of plants | 4 |
| Tabletop garden | A countertop: the light, the planter and the timer in one | 1 |
Grow light bulbs: A19 vs BR30 vs PAR38
All three Zone shapes screw into a standard E26 socket. The letters are the bulb’s shape and the number is its diameter in eighths of an inch, so a PAR38 is the widest. Reflector shapes (BR and PAR) send the light forward, toward the plant; the A19 spreads it around like a household bulb. Check the bulb fits the lamp or fixture before you buy.
| Bulb | Shape | Nominal diameter | Base |
|---|---|---|---|
| A19 grow light bulbZ-GR-A19-3S | A-shape, the everyday household bulb | 2-3/8 in | E26 |
| BR30 grow light bulbZ-GR-BR30-3S | BR, bulged reflector | 3-3/4 in | E26 |
| PAR38 grow light bulbZ-GR-PAR38-3S | PAR, parabolic aluminized reflector | 4-3/4 in | E26 |
Nominal diameter is the standard size for the bulb designation, not a Zone measurement. Watts and output for these three bulbs are added to each product page as the datasheet is confirmed.
