Power Over Ethernet Plug-and-Play Simplicity
LumaG’s Power over Ethernet (PoE) lighting redefines efficiency for controlled environment agriculture. By delivering low-voltage DC power and smart spectrum control directly over Cat6 cabling, LumaG turns nearly every watt into usable photons. The result: 30–80% energy savings, cooler rooms, and precise recipes that boost cannabis yield and quality while slashing HVAC and electrical costs.Understanding Power over Ethernet (PoE) in Grow Lighting
Most cannabis cultivators are familiar with two types of wiring: standard electrical circuits that power high-wattage HID or LED fixtures, and separate low-voltage data cables for controls. Power over Ethernet (PoE) combines these two worlds into one. Instead of running thick conduit for AC power and a second system for control, PoE uses a single Cat5e or Cat6 Ethernet cable to deliver both power and data.
In practical terms, PoE is a low-voltage, direct-current system (around 48 volts DC). Unlike traditional 120–240 V AC wiring, PoE is safer, simpler to install, and far more efficient for LED lighting. Because the power is DC from the start, fixtures don’t waste energy on AC-to-DC conversions at every bar—conversions that normally generate heat. Less wasted energy means cooler fixtures, reduced HVAC demand, and more watts turned into photons.
Another advantage is granular control. Since the same cable carries power and data, each light can be individually dimmed, tuned by spectrum, or scheduled by growth stage—all from a central controller. For growers, this means no more “one-spectrum-fits-all.” Instead, PoE makes it possible to design true light recipes: blue for vegetative structure, red and far-red for flowering, green for canopy penetration.
For cannabis growers who measure success in grams per square foot and grams per watt, PoE isn’t just wiring—it’s a new platform for precision lighting. And this is where LumaG’s PoE Lighting comes in, purpose-built to align with cannabis’ photosynthetic action spectrum.
Introducing LumaG PoE Lighting
LumaG takes the efficiency and simplicity of Power over Ethernet and applies it directly to cannabis cultivation. Instead of broad-spectrum “white light” or narrow-band fixtures limited to just red and blue, LumaG delivers a targeted multi-band spectrum aligned with cannabis’ photosynthetic action spectrum. Each fixture is tuned to deliver photons only in the ranges plants use most: blue, green, red, deep red, and far-red. This means higher photosynthetic efficiency, stronger morphology, and better cannabinoid and terpene expression.
Each LumaG bar draws just 75 watts, yet delivers 400 PPFD at canopy while running cool at only 72 °F. With PoE wiring, intensity scales easily: a 4′ x 8′ grow can support up to 13 eight-foot light rails, reaching around 1,200 PPFD—a proven high-yielding range for cannabis. Even at these levels, growers cut power costs by roughly 25% compared to standard LED setups because there’s less conversion loss and less HVAC burden.
What makes LumaG different is control. Through the PoE backbone, growers can adjust spectrum and intensity per zone and per growth stage. That means blue-heavy light for compact vegetative growth, red and far-red for accelerated flowering, and green to drive light deeper into the canopy for more uniform bud development.
The result is not only higher yields per square foot, but also better consistency and higher quality. With LumaG, growers buy only the photons their crop can use—nothing wasted, everything optimized.
Smarter Cultivation with PoE Lighting
-
Targeted Spectrum
Every photon counts
Blue, green, red, deep-red, and far-red wavelengths are tuned to plant biology, ensuring nearly every photon contributes to photosynthesis.
-

Smarter grows, better results
Networked control enables precise scheduling of intensity, spectrum shifts, and per-zone recipes, helping growers maximize yield quality with minimal effort.
Why PoE Lighting Delivers 30-80% Savings
LumaG’s PoE lighting system is tuned to deliver maximum performance within the 90–100 W per-port limit set by Power over Ethernet (PoE++) standards. The 75 W fixture design is not arbitrary—it’s the most powerful configuration that can be powered safely and efficiently using standard PoE infrastructure, eliminating the need for bulky drivers or complex AC wiring at each light.
The LumaG Difference
By centralizing AC-to-DC conversion in a high-efficiency PoE switch rather than at each fixture, LumaG lights avoid the losses associated with dozens of conventional power supplies—dramatically increasing overall system efficiency. Studies show PoE lighting systems can keep cable and transmission losses under 5% (for typical runs under 50m), resulting in highly streamlined energy delivery

Cooler Operation Leads to Lower Cooling Bills
Operating at under 72 °F, LumaG lights release minimal heat into the canopy. Cooler lights reduce HVAC load, enable closer placement to plants for higher light uniformity, and prevent photochemical degradation (like terpene loss) An LED’s cooler footprint represents both direct energy savings and improved environmental control—translating into real operational cost reductions.
