About this file
This is a Questions and Answers document for a federal contract opportunity (12639526Q0206) regarding greenhouse lighting and infrastructure modifications.
The document addresses four primary inquiries concerning a large greenhouse facility at Building 1398. Regarding lighting, the facility does not have established Daily Light Integral (DLI) averages and the existing 24 lamps are deemed insufficient for seedlings and young shoots during winter months. The facility is considering transitioning to an ARIZE Element L2000 lighting system, and the response requests specifications for determining the quantity of lights needed to support plant growth in designated areas. For heater positioning, the response indicates that heater units at both ends of the greenhouse extend 5.5 feet, recommending a 6-foot clearance from door walls for lighting architecture planning. Regarding frame requirements, the internal structure should accommodate standard aluminum simple frame additions with no specific anchor point restrictions noted. On electrical infrastructure, Building 1398 has two main breakers providing 100V each to the greenhouse panel box, which contains 20 breakers rated at 20W each for current lighting and ventilation controls. The heater units operate at 115V single phase, while a separate west-side panel box provides maximum voltage of 208V three-phase at 60Hz frequency.
The document also includes comprehensive product specifications for the ARIZE Element L2000 lighting fixture, an LED-based horticultural lighting system available in 2 or 3 module configurations with input voltage ranges from 120-480V. The fixture delivers a maximum Photosynthetic Photon Flux (PPF) of 3400 μmol/s in the 3-module high-output configuration with efficacy ratings between 2.7 to 3.5 μmol/j. Available spectrum options include Pink Extremely Low Blue (PKT), Pink Low Blue (PKR), Pink Medium Blue (PKB), Pink Far Red (PKF), and White Medium Blue (BRI). The system includes 0-10V dimming capability, IP66 listing, passive thermal management, and a five-year limited warranty with a rated life exceeding 50,000 hours.

RFIs and Responses, 12639526Q0206
- Do you have a target DLI for the greenhouse? (or do we base this one on the actual lighting system + sun supplemental light, meaning ((24) 450W bulbs).
We do not have DLI averages for the large greenhouse. The 24 lamps that we do have do not seem very good for seedlings or young shoots through the winter. Growspan recommended we switch to a light system like ARIZE Element L2000. See next pages for specs. If we go with that light or something close to it, all we want to know is how many lights we need to give good growth to any plants placed in that large greenhouse (in particular the areas diagramed in pink).
- Do you happen to know the overlap of the heater over the bench? (this to potentially modify the position of our first iteration of lighting architecture.)
The heaters at both ends extend at 5.5 ft so I would allow 6ft from the door walls.
- Frame-wise, do you have any specific requirements and anchor point needs?
The frame internally should accommodate any aluminum type simple frame additions.
- Electric-wise: 4 circuits on 20-amp breakers, is it 208V or 120V? (I got confused).
Building 1398 has 2 main breakers running to that greenhouse 100V each. The greenhouse panel box has 20 breakers at 20W each. These are for current lighting and vent controls. The heater units say 115V single phase on their sides. Another panel box on West side of greenhouse says the max voltage is 208V -3 phase at Freq 60HZ.
