Treegers GB30W LED Grow Bulb | E27 | Full Spectrum 4800K | 30W | 5-Year Warranty

Twice the Power. Same Simple Screw-In Fit.

The Treegers GB30W LED Grow Bulb is the heavy-hitter in the Treegers range. At 30W with a 60 µmol/s PPF output — double that of the GB15W — it’s built for growers who need serious light coverage from a single E27 socket. Bigger plants, bigger pots, bigger yields — same plug-and-play simplicity.

The 4800K full spectrum and 90+ CRI deliver light that’s close to natural sunlight, supporting every stage of growth from seedling to harvest. And because it looks natural and warm, it fits right into your home without turning it into a grow room.

Works for a Wide Range of Plants

Seeds and seedlings, fresh herbs, leafy greens, decorative plants, flowers, and fruiting plants like tomatoes, cucumbers, and peppers — the GB30W’s full spectrum supports every growth stage. With double the PPF of the GB15W, it’s especially well suited to larger pots, taller plants, and setups where you need more light from a single point.

Premium COB LED Technology

Inside the robust aluminium housing is a high-quality COB LED chip — the same technology used in professional grow lights. COB LEDs concentrate more light into a tighter 60° beam, so more of that energy reaches your plants where it counts. The passive cooling design means no moving parts, no noise, and no maintenance.

GB15W vs GB30W — Which One Do You Need?

The GB15W is perfect for smaller plants, seedling trays, herbs, and compact setups. The GB30W is the right choice when you need more coverage, are growing larger or taller plants, or want to maximise output from a single socket. Both share the same E27 fit and 4800K full spectrum.

Perfect For

Home growers, apartment gardeners, and plant enthusiasts who want serious grow light performance from a standard lamp fitting — no grow tent, no special wiring, no complicated setup.
