320W of Top Light for Dutch Orchids: Why Flower Growers Are Retiring HPS
A Dutch orchid grower lights the crop with 320W Toplight-G3 top lights — high-output LED built to replace older HPS installations.
Orchids are a demanding crop to light. The flowers are the product, so the light has to be even across the whole bench — uneven light shows up as uneven flowering. And orchids dislike heat on the canopy, which is exactly what HPS throws at them. To keep the heat off, HPS lamps have to hang high, and the light that reaches the flowers is weaker and less even.
The Toplight-G3 is built for that retrofit. It is a high-output top light, 320–640W, with a modifiable spectrum — the light can be tuned to the crop's stage, and for orchids that means light set for flowering. LED runs cooler than HPS, so the fixture can sit closer to the crop and the canopy gets a more even spread of light.
In the Dutch orchid house, the 320W G3 is the top light. The grower keeps the HPS-era layout — the LED top light drops into the place the old lamps occupied — and the spectrum is set for the flowering stage.
For a flower grower, the case for LED top lights is not only about power. It is about evenness: every stem on the bench getting the same light, so the crop flowers together. That is what a top light with a tuned spectrum is for.
