The Digital Light Meter is essential for accurately determining if your plants are receiving what they need for healthy growth and maximum production. Includes a life-time battery, recommendations and a convenient carrying case.

Unique Features:

• Measures both HID lamps and sunlight

• Measures up to 40,000 foot-candles

• Convenient hand-held remote sensor

• 3 scales for precise readings

• Lifetime silicon cell

Grower’s Tip:

As MH and HPS bulbs age, their intensity drops, lumen output decreases and foot-candle (a measurement of illumination) readings weaken. Bulbs should be replaced every 6 to 12 months, regardless of the number of hours they’re rated for.
