Drummond
Series DAIRY
Precision lighting for healthier, more productive herds
The Drummond Series Dairy Light is purpose-built to help dairy farmers enhance herd welfare, increase milk yields, reduce energy costs, and ultimately drive farm profitability.
Each fitting features two distinct output modes: white and red. The white light uses specialist LED chips designed to closely replicate the natural daylight spectrum, supporting cow productivity and well-being during daylight hours. The red light enables effective night-time monitoring without disrupting the animals’ circadian rhythm, maintaining a calm and stress-free environment.
The combination of both light modes within a single unit, along with dual individually controllable circuits, allows for straightforward installation and flexible operation via time-clock, photocell, or a combination of the two. The Drummond Series is available in four carefully engineered light distributions, ensuring efficient and effective illumination tailored to a range of shed configurations, mounting heights, and spacing.
A rugged, shock-resistant aluminium housing with a marine-grade powder-coated finish ensures durability in demanding agricultural environments. With a 10-year warranty, the Drummond Series delivers long-lasting performance, reliability, and energy efficiency for the modern dairy operation.

The Drummond Series Dairy Light has several features uniquely tailored to dairy environments, including:
Integrated Red + White LED Output: Combines high-efficacy white lighting (cost-effectively delivering 200 lux) with red night-mode LEDs - supporting cow circadian rhythms. Red lighting allows night-time checks without disrupting melatonin cycles, aiding fertility and milk yield.
Precision Photobiological Light Control: Paired with time clocks, the lighting system can provide consistent photoperiod lighting, supporting long-day photoperiod management (e.g. 16 hours light / 8 hours dark) to boost milk production.
Uniform, Glare-Free Illumination: Special optics provide uniform distribution across stalls and feed alleys with reduced glare, improving cow comfort and visibility for farm staff.
Rugged and Waterproof for Washdowns: Dairy barns require regular pressure washing. The Drummond light is fully sealed to IP66 with corrosion-resistant construction, tolerating wet, ammonia-rich environments.
Plug-and-Play Control Options: Available with integrated controls like daylight sensors, dimming protocols, and timing systems—making it easy to implement lighting regimes specific to different herd stages (e.g. lactation vs dry cows).
Smooth, Hygienic Design: Designed with a cleanable, smooth housing—no fins or crevices—minimising dust, insect, and bacterial build-up. This makes it ideal for hygiene-sensitive areas like milking parlours and calf housing.
