LED Illumination Chamber 250-450 L, Up to 20000 lx, 4 to 50°C, Plant Growth Chamber with Defrost

The Master Science LED Illumination Chamber recreates light and temperature conditions for plants, seeds, insects and cell cultures. LED cold light reaches up to 12000, 15000 or 20000 lux depending on size and can be set in six steps, while the chamber holds 4 to 50°C without light or 10 to 50°C with the lights on.

Air is drawn in at the back and supplied from below by a large-impeller fan, and the shelves are laser-perforated so it flows evenly around the samples. A three-stage automatic defrost keeps ice from upsetting temperature during cold runs. The LCD controller handles fixed-value and timed running, with an optional program of 30 segments and 100 cycles for day-night cycles.

Key Benefits

• Strong, adjustable light: The Master Science LED Illumination Chamber delivers up to 20000 lux in six selectable levels.
• Stable at low temperature: Automatic three-stage defrost prevents frost-related drift.
• Even conditions on every shelf: Back-suction, bottom-supply airflow and perforated shelves.
• Simulate day and night: Optional 30-segment programs vary light and temperature over time.

Growth Study Problems the Master Science LED Illumination Chamber Solves

Window sills and greenhouses give unpredictable conditions. The Master Science LED Illumination Chamber addresses:

• Inconsistent light levels: LED lighting is set in fixed, repeatable steps.
• Temperature swings in cold runs: Automatic defrost keeps the chamber steady.
• Uneven growth between shelves: Engineered airflow evens out temperature.
• Manual day-night switching: Programs automate light and temperature cycles.
