01
DMX (Digital Multiplex)
Entertainment Technology — USITT DMX512-A — Asynchronous Serial Digital Data Transmission Standard For Controlling Lighting Equipment And Accessories
(ANSI E1.11 , DMX512/1990 , EIA-485)
02
RDM (Remote Device Management)
Entertainment Technology — Remote Device Management Over DMX512 Networks, describes a method of bi-directional communications over a USITT DMX512/1990 or ANSI E1.11 - 2004 data link.
(ANSI E1.20 )
03
ARTNET (Remote Device Management)
Entertainment Technology -- Art-Net is a royalty-free, open-source protocol that allows DMX512 and RDM lighting data, distributes multiple universes of DMX-512 data over IP-based networks
04
1-to-10v / 0-to-10V (Analog Dimming)
Entertainment Technology — It uses a continuously variable DC voltage signal (1-10 volts or 0-10 volts) to control the brightness of a lighting fixture.
(ANSI E1.3)
05
DALI (Digital Addressable Lighting Interface)
It is a two-way open protocol – a digital, internationally adopted language used to control lighting such as LED Drivers.
(IEC60929)
06
MQTT (Message Queuing Telemetry Transport)
It is an OASIS standard for IoT connectivity. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks.
07
Plant lighting (Grow Lights)
PPFD (μmol/m²/s)
measures the density of PAR (Photosynthetically Active Radiation 400–700 nm) hit a specific area (per second). It is not the same as lux/lumens (which measure human-visible light, not plant-useful light).
oRecommended PPFD Ranges:
Seedlings/Clones: 100–300 μmol/m²/s
Vegetative Growth: 300–600 μmol/m²/s
Flowering/Fruiting: 600–1000+ μmol/m²/s
PPF (μmol/s)
the total amount of PAR (Photosynthetically Active Radiation, 400–700 nm) light emitted by a grow light per second. Its how much plant-usable light a fixture produces, not how intense the light is at the canopy level (that’s where PPFD comes in).
08
Circadian Rhythm (our 24-hour biological clock)
is strongly influenced by light exposure, particularly in the blue spectrum (460–490 nm). The right light can improve alertness, mood, and sleep, while the wrong light can disrupt melatonin production and harm health.
09
ipRGCs (Intrinsically Photosensitive Retinal Ganglion Cells)
are specialized neurons in the retina that express the photopigment melanopsin, making them sensitive to light even in the absence of rod (scotopic) / cone (photopic) input.
