Frequently Asked Questions


This is the list of most commonly asked questions about LED grow lights.

Most lamps are dimmable.

  • C-Series, BX-Series & LightDNA – dimmable by default
  • R-Series – optionally dimmable
  • L-Series, BL-Series – not dimmable

All spectra can be placed in any of the luminaries, based on your request. The choice of luminaire depends on the physical space you are growing plants in (greenhouse, growth chamber etc) and the choice of spectrum depends on what you are growing and in which stages.

Once you tell us where and what you are growing we will advise on the optimal luminaire and spectrum. Our expertise is based on extensive in-house and outsourced research and our spectra are suitable for most plants bred globally.

No. When you place an order, luminaires with spectra inside are manufactured for you and thus not changeable later. If your application requires flexibility, please look into our LightDNA product line, which is a line of luminaires with multiple light channels in each, enabling you to re-create whichever light spectrum you may need, using a simple software interface. More information on our  Solutions page.

Yes. Once you tell us what you are planning to grow our resellers or our biologists will advise you on the optimal spectrum for your particular need.

They are not. LED technology consumes significantly less electricity and lasts much longer, thus in the long run LED grow lights are not more expensive. On top of that, LED grow lights result in better crop, further adding to your savings.

The number of luminaires needed is part of a sophisticated calculation called ‘light planning’ which our resellers do for our potential clients free-of-charge. Some of the information we need for this calculation is:

  • type of plant being bred
  • surface size
  • desired output etc.

We then produce a light plan with an exact number of luminaires as well as their placement (distance from plants, density, positioning etc). This calculation is done with our proprietary light planning technology and is based on hundreds of large scale research trials.

Valoya’s technology was born out of genuine interest in sun substituting light. LED grow lights are not an extension to our main product portfolio, nor the trend we joined. LED grow lights are what we do, what we specialise in and it is an industry we helped create. One fifth of our full time staff are biologists, continuously researching the interaction between light and plants. When you acquire Valoya products, you get with them our expertise in the field of photobiology as well.

Our standard delivery time is 8 weeks. This is for products that need to produced from order, usually BX-, BL- , R-, and C-Series. Products in stock are usually shipped within the next couple of working days and shipping time depends on the final destination.

Our products are made from order. We only keep a small spare / sales stock of selected items.

When you want to replace your old T8 tube with a Valoya L-series tube you get a replacement for the magnetic ballast starter. For other installations you can use end caps. We have end caps with IP ratings of 64 and 67. Valoya tubes only have AC current on one end of the tube, the other end is supplied with a “dummy-end”.

Other series lamps come with standard hooks/hangers/chains, but you can order optional ones. Please see our product brochure on the Brochures & Guides page to see all the products and accompanying accessories.

Check this information from your local Valoya reseller or the Valoya sales team. Please go to the Contact page to find your nearest reseller or to contact Valoya directly.

We offer a 3 year limited warranty on all our products. Optional 5 year warranty is available on certain products.
