What the GM100 High Bay is for
A 100W screw-in UFO lamp on a standard E26/E27 base, 340mm across and 380 grams. It is not a specified horticultural fixture and does not pretend to be — it is the fastest way to put horticultural light into sockets that already exist, in greenhouse aisles, propagation halls and utility spaces where rewiring for a driver-fed fixture is not worth the disruption.
What you get
- Standard E26/E27 screw base — installs into existing sockets with no driver, no hanging hardware and no electrician.
- 100W lamp, Ø340 × 175mm.
- 380g net weight — light enough for existing lampholders and pendant runs.
- Aluminium and PP construction for heat dissipation at lamp scale.
- Steps down to the GM50 at 50W and Ø297mm on the same base and the same construction.

Before you spec it
When should I use a screw-in lamp instead of a proper fixture?
When the sockets are already there and the light is supplementary. Greenhouse walkways, propagation halls, secondary rooms, seasonal top-ups. For any room where you are working to a canopy PPFD target, use a fixture with a published photometric file — the GK series if you want a high bay, a panel or bar fixture if you have benches.
GM100 or GM50?
Same base, same materials, two sizes: 100W at Ø340mm against 50W at Ø297mm. Choose on mounting height and the spacing of the sockets you already have.
Is there a spectrum specification?
Not a documented one. This is the honest limit of the GM range — we can tell you the wattage, the base, the size and the weight, and nothing more that we can stand behind. If spectrum matters to the application, it is the wrong product.
Can it be dimmed or group-controlled?
No dimming or control interface is specified. It is a lamp: it is on or it is off, on whatever circuit the socket is on.
