Full Spectrum PhysioSpec Indoor for optimal photosynthetic targeting.

BML Lighting SpydrX is now Fluence SPYDRx a 340W LED indoor grow light with an average – not max – PPFD above 455 is perfect as an vegetative-stage, top-lighting solution for commercial applications, and as a full-cycle top-lighting solution for residential applications without CO2 addition. Designed and built in Austin, TX. Anodized, extruded aluminum alloy chassis with integrated heatsink for longevity and passive, natural convection thermal management (no fans or moving components).

PhysioSpec Indoor Spectrum

Fluence SpyderX Plus Spectrum IndoorChart

Fluence's spectra wavelengths are tailored for particular photomorphogenic responses, photoperiodic signals, chlorophyll A and B absorption, xanthophyll carotenoid pigments, and anthocyanin accumulation in plant tissue – along with unknown photoreceptors – to name a few.

To create the most advanced spectrum for complete physiological plant growth, Fluence had to challenge every assumption. Not only did this make the spectra better, it made it beautiful. Previously, 700nm (red) and 400nm (blue) were the most efficient LED packages, and coincided with peak Cholorophyll A and Cholorophyll B absorption areas. This led to a negligence of key photoreceptors and pigments outside this range.

Fluence PhysioSpec Indoor is a full-cycle spectrum optimized for rapid growth and complete plant development. Tailored for growing plants from initiation to senescence (germination, clones/cuttings, mothers, vegetative and flowering applications) in indoor environments. With a CRI rating of 85, Fluence PhysioSpec Indoor offers a beautiful work and research environment with vivid colors and greater contrast to study the health of your crop.


Amperage depends on fixture wattage (685W for SPYDRx PLUS) and input voltage. Below is a general estimate. Actual figures may vary.

  • Amps @ 120V: 2.8A
  • Amps @ 208V: 1.6A
  • Amps @ 240V: 1.4A
  • Amps @ 277V: 1.2A

  • Usage

    Recommended mounting height 6 inches from top of canopy for best canopy penetration, optimal light uniformity, and flux density above a 4ftx4ft canopy.

    Suitable for operation in still air ambient temperatures from -40°C (-40°F) to 35°C (95°F) when suspended and up to 30°C (86°F) when surface mounted. Operating temperature ranges between 25°C (77°F) to 30°C (86°F) above ambient.

    Sufficient air flow will increase the maximum suitable operating temperature and help extend lifetime of this lighting system. Fluence Bioengineering recommends at least one ft3/S of airflow to ensure efficient cooling.
