LED Plant Growth Chambers with Specialized Lighting
In many plant experiments light is the variable being tested. Spectrum, intensity, photoperiod and uniformity all change how a plant grows, flowers and responds to stress, so an LED plant growth chamber for research should give you precise, repeatable control of each one.
JKG supplies growth chambers with Percival’s specialized LED lighting systems: SciBrite for adjustable spectrum, SciWhite for high-intensity white light, and IncuWhite, IncuBrite and PetriClear for incubators and tissue culture. Every system can be fitted to chambers of any size, from bench-top units to walk-in rooms.
Lighting systems
LED Growth Chamber Lighting at a Glance
Six lighting systems cover plant growth, light-quality research, incubation, marine work and tissue culture. Intensity is measured 15 cm (6 in) from the lamps.
| System | Spectrum and control | Intensity at 15 cm | Best suited to |
|---|---|---|---|
| SciBrite LED | Four or eight colours; the standard four are blue, red, white and far-red. Each colour dims from 1 to 100% in 1% steps, by tier. | Up to 1,850 µmol/m²/s standard; 2,100 µmol/m²/s or higher on request | Light-quality and photomorphogenesis studies, specific wavelengths |
| SciWhite LED | White spectrum enriched with red, 660 nm peak (blue 14%, green 41%, red 42%, far-red 3%). Dims from 10 to 100% in 1% steps. | Up to 1,700 µmol/m²/s | General plant growth, seed germination, plant pathology, indoor farming R&D |
| SciWhite for Marine | Two channels: one blue-rich for coral, one white with 450, 660 and 730 nm peaks for marine plants. Nano-coated against water and dust. | By configuration | Coral, phytoplankton, kelp and marine algae |
| IncuWhite LED | White LEDs matched to natural light for incubators. Flicker-free, dimmable in 1% steps, protected against dust and water. | 100–230 µmol/m²/s, by model | Incubation, insects, seedlings, low-light photosynthesis |
| IncuBrite LED | Supplemental colours: UVA 380, violet 420, blue 450, green 520, orange 620, deep red 660 and far-red 735 nm, by shelf or whole chamber. | Supplemental | Low-light work; red light for insects, which cannot see red |
| PetriClear | Dual-channel white (6000 K, CRI 90) and infrared LEDs; infrared warms Petri dish lids above dew point to prevent condensation. | 170–200 µmol/m²/s | Plant tissue culture, fungi, bacteria and yeast |
SciBrite LED
Light Quality Plant Growth Chambers
SciBrite LED chambers are built for experiments that need specific wavelengths. A multi-channel dimming system controls each colour from 1 to 100% in 1% steps, so you can build your own spectrum, change it through the day, and run different settings on each tier.
- Up to 2,100 µmol/m²/s or higher
- Four-colour (blue, red, white, far-red) or eight-colour configurations
- Independently dimmable tiers
- Programmed from the IntellusUltra touchscreen

Light measured 15 cm (6 in) from the LEDs; temperature range with all lights on. SciBrite panels can also be added to SciWhite, Arabidopsis, low-temperature and tissue culture chambers.
Benefits of LED Growth Chamber Lighting
Compared with fluorescent lamps, SciBrite and SciWhite LEDs give:
More control over colour composition and intensityLess demand on the temperature control systemImproved humidity control and temperature uniformityMore uniform light distributionSmaller day/night calibration offsetsLower energy use and less heat rejected to the roomLonger life for key chamber componentsMore growing height inside the chamber
Options
Lighting Options and Upgrades
Available on JKG-41, JKG-66 and Percival chambers, depending on the model.
Top-tier upgrades
Upgrade the top tier to 1,000, 1,200, 1,500 or 2,000 µmol/m²/s, or to 2,100 µmol/m²/s and higher, for high-light crops.
Independently dimmable tiers
Set each shelf to its own light level as a percentage of output, and run several light treatments in one chamber.
Closed-loop PAR control
A PAR sensor feeds back to the dimming system to hold a set intensity as lamps age.
Daily light integral
Programme light by the total photons delivered per day rather than by intensity and hours alone.
Supplemental LEDs
Add white, red, blue or far-red LEDs, or IncuBrite colours, to tune a SciWhite chamber’s spectrum.
Eight-colour SciBrite tile
Blue, red, warm white, far red, green, cool white, photo red and violet in one programmable tile.
LED working light
A light that switches on when the door opens, so you can work without disturbing the photoperiod.
UV, germicidal and aquatic lighting
Specialty lamp banks for UV exposure studies, surface decontamination and aquatic research.
Buying guide
How to Choose Growth Chamber Lighting
Species and growth stage
Light needs differ widely, from low-light Arabidopsis and lettuce to high-light cereals and fruiting crops.
The question you are asking
A light-quality study needs adjustable colour channels; routine growth needs dimmable white light.
Intensity at plant height
Specify the PPFD you need at canopy height. Intensity is quoted 15 cm from the lamps and falls with distance.
Number of tiers
Independently dimmable tiers let you run different light levels in one chamber; each tier reduces growing height.
Measurement
Chamber settings and what reaches the leaf can differ. A spectroradiometer or quantum sensor shows what plants receive.
Heat load
Light adds heat. LED lighting reduces it, but check the chamber holds your temperature range at your intensity.
Measure what your plants receive
Light Measurement and Plant Response
Pair your chamber with PSI instruments that measure light spectra and photosynthetic response, such as the SpectraPen and FluorPen ranges.

FAQ
Frequently Asked Questions
Answers to the questions we hear most. Can’t find what you need? Our team will help.
What is an LED plant growth chamber?
A controlled-environment chamber that uses LED lamp banks instead of fluorescent lamps. LEDs give finer control of intensity and spectrum, add less heat, and improve temperature and humidity control.
Is the lighting dimmable?
Yes. SciBrite colours dim from 1 to 100% in 1% steps, SciWhite from 10 to 100% in 1% steps, and tiers can be dimmed independently as an option.
What is the maximum light intensity?
SciBrite reaches 1,850 µmol/m²/s and SciWhite 1,700 µmol/m²/s at 15 cm as standard, and LED lighting can be configured to 2,100 µmol/m²/s or higher. LED configurations of 2,100 µmol/m²/s or higher are available on JKG-41 and JKG-66 chambers.
Which lighting suits Arabidopsis?
Arabidopsis chambers come standard with SciWhite LED lighting, with SciBrite as an option for light-quality work. See Arabidopsis chambers.
Can I change the spectrum of a SciWhite chamber?
Yes. Supplemental IncuBrite or SciBrite LEDs can be added to tune the spectrum, or to give one shelf or the whole chamber a specific wavelength.
Can walk-in rooms have SciBrite lighting?
Yes. Walk-in growth rooms can be fitted with SciBrite or SciWhite LEDs, with independently adjustable columns or tiers. See walk-in growth rooms.
What is a daily light integral option?
It lets you programme light by the total photons delivered over a day (mol/m²/day) rather than only by intensity and hours.
