The listings feature a mix of full-spectrum white light and specialized red-blue spectrums. These are often used as 250W or 600W equivalents in traditional lighting terms, offering higher efficiency for indoor hydroponics and soil-based pots.

Available fixture formats

These listings cover several physical configurations to match different growing environments. Most models include integrated controllers for light management.

Technical specifications and brands

Many units offer 10 dimmable levels and specific 660nm plus 460nm wavelengths for flowering and vegetative stages. Use these listings to compare physical dimensions and mounting hardware before visiting the brand pages.

The directory helps identify which 40W models include built-in timers and which require external switches. Click a specific listing to view the full technical data and current availability on Amazon.
