Description
Mushrooms don’t photosynthesize — but they still need a light cue to trigger fruiting, keep stems growing straight, and let caps form normally instead of stretching toward the nearest window. The Grower’s Select LED Mushroom Light Bulb is the same dual-spectrum light engine used in our Mushroom Lighting Kit, sold on its own for growers who already have an E26/E27 fixture — a lamp, clip light, or work light — and just need the right bulb.

Why Growers Choose This Bulb
Generic grow lights are built for photosynthesis — bright, hot, and tuned to a spectrum mushrooms don’t need. This bulb alternates 6350K diodes to stimulate pinning and fruiting with 5000K diodes that hold a natural daylight rhythm, at only 15 watts of actual draw. It screws into any standard E26/E27 socket, so if you already have a fixture over your grow space, this is the only piece you need to add.
What's in the Box
- 1x 48-diode dual-spectrum LED bulb (alternating 6350K and 5000K diodes)

How to Set Up Your Light Bulb
- Screw the bulb into any standard E26/E27 fixture — a clip light, work light, or lamp.
- Position the light 12–18 inches from your grow chamber, angled to reach the whole surface.
- Run it on a 12-hour-on/12-hour-off cycle — a plug-in timer automates this so you don’t have to.
Frequently Asked Questions
Does this bulb come with a socket or adapter?
No — this listing is the bulb only, for growers who already have an E26/E27 fixture (a lamp, clip light, or work light) to screw it into. If you don't have a fixture yet, our Mushroom Lighting Kit bundles the same bulb with a universal socket adapter you can plug straight into an extension cord or outlet.
Do mushrooms actually need light to grow?
Mushrooms don’t photosynthesize, so light isn’t food for them — but it is the signal that tells colonized mycelium to stop running and start fruiting. Light also keeps stems growing straight and caps forming normally instead of stretching toward a light source. A consistent daily cycle, even from a small bulb like this one, is what actually matters.
What fixtures does this bulb fit?
Any standard 110V E26 or E27 base — the same size used in most household lamps, clip lights, and work lights.
Will this bulb make my grow chamber too hot or dry it out?
No. At 15 watts of actual draw, this LED runs cool enough for enclosed spaces like monotubs and tents, unlike incandescent bulbs or plant-grade grow lights, which run hot and can dry out a fruiting chamber.
How many hours of light should I run it?
Most growers run a 12-hour-on/12-hour-off cycle to mimic a natural day/night rhythm. A plug-in timer keeps the cycle consistent without you having to remember to flip a switch — see our 24-Hour Heavy Duty Timer.
