Frequently Asked Questions

What is a Growlush HPS Lamp used for?

It provides high-intensity horticultural lighting for indoor and greenhouse plants. Its warm spectrum is particularly useful during flowering and fruit production.

Is this lamp suitable for seedlings?

HPS lamps can be used throughout a plant’s growth cycle, but their high intensity and heat output may be excessive for young seedlings. Lower-intensity lighting is generally easier to manage during propagation.

Does the lamp require a ballast?

Yes. The lamp must be operated with a compatible HPS ballast rated for the same wattage.

Can I use the lamp with any reflector?

Use only a reflector and lamp holder designed for the lamp type and selected wattage. Check compatibility before installation.

Does an HPS lamp produce heat?

Yes. HPS lighting produces substantial radiant and ambient heat. Adequate ventilation, safe hanging distance and temperature monitoring are essential.

Is the ballast or reflector included?

Package contents vary between listings. Check the selected product variant to confirm whether the purchase includes the lamp only or a complete lighting kit.
