The difference between buying lights and solving lighting problems matters.
A comprehensive lighting proposal isn’t just a price list. It’s a detailed plan that explains spectrum choices, addresses your specific facility constraints, maps expected light distribution across your entire growing space, covers power architecture and installation, discusses incentive programs, and outlines ongoing support. Many suppliers skip these details. The best ones don’t.
The Core Components:
Spectrum Design With Reasoning
- Why specific percentages of each color (blue, green, red, far-red) matter for your crops
- How spectrum choices affect photosynthetic efficiency and plant quality
- Why undercanopy lighting changes top-light spectrum recommendations
- Trade-offs between different spectral options and their costs
Top and Undercanopy Strategy
- How top lights and undercanopy lights work together
- Whether undercanopy placement should be on rigid stands, adjustable stands, on pots, etc.
- Specific intensity targets for different growth stages and plant areas
- Genetics-specific considerations (photobleaching risk, quality goals, etc.)
Power Architecture
- How many lights daisy-chain together
- Where power drops should be positioned
- Voltage options compatible with your facility
- Installation simplicity and maintenance implications
PPFD Mapping and Uniformity
- Projected light intensity across your entire growing space
- How edge effects are addressed (not just peak brightness at center)
- Wall reflectivity and long-term light loss calculations
- Real average intensity where plants will actually grow
Beyond the Fixtures
- Utility incentive programs specific to your region
- Control system integration and compatibility
- Installation guidance and support
- Service commitments if equipment fails
- Staff training for optimal use
Why It Matters:
Every facility is different. Templates don’t work. Suppliers who take time to understand your specific operation, explain their reasoning, and commit to ongoing support deliver better results than those who just take orders.
When evaluating lighting proposals, look for detailed explanations, not just specifications. Ask how they’ll support you through installation and beyond. That’s the difference between buying lights and solving lighting problems.
