Heliospectra Grow Light Alternatives: MITRA X Replacement Solutions
Heliospectra Grow Light Alternatives for Existing Greenhouse Projects Replace or upgrade existing MITRA X, C3, C4 and FLEX grow light systems with solutions developed around your required spectrum, output, mounting layout and control strategy.
Heliospectra grow lights can be replaced, but a successful replacement requires more than choosing a fixture with similar wattage. Spectrum, PPF, efficacy, canopy PPFD, dimensions, mounting points, electrical connections and control architecture must all be reviewed.
This guide explains the main replacement paths for Heliospectra MITRA X, MITRA X C3, MITRA X C4 and MITRA X FLEX systems. It also helps greenhouse operators determine whether they need a performance replacement, a physical retrofit replacement or a complete lighting and control system migration. If you are seeking a reliable heliospectra alternative, evaluating a heliospectra grow light replacement, sourcing a MITRA X replacement, or exploring a long-term commercial greenhouse grow light alternative, matching optical and mechanical engineering specs is essential for ongoing production continuity.
Heliospectra grow lights can be replaced, but the extent and complexity of the replacement depend on the existing fixture model, spectrum requirements, mounting structure, power supply setup, and control architecture. Certain commercial greenhouse projects only require reproducing the original crop lighting performance and target canopy photon flux density (PPFD). Other projects require an exact physical retrofit that matches existing mounting hole distances, unistrut brackets, power cord exit directions, and waterproof electrical connectors.
To help greenhouse operators evaluate their options, replacement strategies are generally grouped into three distinct paths:
Performance Replacement: Focuses primarily on matching optical output, spectral power distribution (SPD), total photosynthetic photon flux (PPF), canopy PPFD, beam distribution, and overall crop development goals. Fixture dimensions, mounting points, or wiring layouts may be adapted to modern greenhouse configurations.
Physical Retrofit Replacement: Extends optical performance matching to include physical and electrical dimensions. The replacement fixture is engineered to align with existing mounting points, truss spacing, electrical cabling, and quick-connect pinouts to simplify on-site installation.
System Migration: Involves replacing the lighting fixtures while re-architecting the control framework—such as transitioning from legacy control platforms to modern 0–10V, DALI, or RS485/Modbus wired and wireless control networks.
Important Constraint: Replacement suitability must always be verified on an engineering basis. A replacement fixture cannot be selected based on input wattage alone. Furthermore, matching performance does not automatically guarantee direct plug-and-play mechanical compatibility without technical verification.

What Happened to Heliospectra AB?
Heliospectra AB officially resolved to file for bankruptcy on July 27, 2026. The bankruptcy application was submitted on the same day to the Gothenburg District Court, which approved the application and declared the company bankrupt. Consequently, the company’s shares were delisted from the Nasdaq First North Growth Market.
For existing commercial greenhouse operators, this development necessitates a re-evaluation of long-term operational risks. Facilities relying on installed Heliospectra systems must assess ongoing spare parts availability, fixture expansion continuity for future phases, technical support access, and long-term control system maintenance risks.
What Existing Heliospectra Customers Should Consider
Before selecting a replacement fixture, greenhouse facilities managers and head growers should perform a thorough site audit. Gathering comprehensive electrical, optical, and mechanical data upfront prevents operational delays and installation bottlenecks.
Existing users should compile the following technical checklist:
Model Identification & Quantity: Exact Heliospectra fixture model (e.g., MITRA X, MITRA X C3, MITRA X C4, MITRA X FLEX) and total unit count.
Operational Status: Count of damaged or failing fixtures versus units operating normally.
Electrical Parameters: Input line voltage (e.g., 230 VAC, 277 VAC, 347 VAC, 400 VAC, 480 VAC), rated power consumption (W), and electrical circuit breaker loading capacities.
Optical Output Data: Original spectral power distribution (SPD) files, total fixture PPF (μmol/s), and photon efficacy (PPE in μmol/J).
Canopy Metrics: Target canopy PPFD (μmol/m²/s) and Daily Light Integral (DLI in mol/m²/day) required for specific crop varieties (leafy greens, herbs, tomatoes, cucumbers, or propagation).
Replacement Scope: Whether the facility requires immediate partial replacement of failed units or a phased zone-by-zone upgrade.
Important: Do not select a replacement fixture based only on wattage. Two grow lights with the same input power can produce different spectra, photon output, beam distribution and canopy PPFD.
Heliospectra Grow Light Replacement Options
To streamline technical evaluation, the table below maps primary Heliospectra LED series to their main operational characteristics and core replacement objectives:
Existing Heliospectra System
Main Characteristic
Primary Replacement Goal
MITRA X
Fixed-spectrum portfolio with scalable modular configurations (325W–1500W)
Match light output, target spectrum, fixture dimensions, and greenhouse layout
MITRA X C3
Three independently adjustable channels (Base PAR + Horti-White + Far-Red)
Preserve practical multi-channel spectrum adjustment with simplified channel control
MITRA X C4
Four independently adjustable channels (Red, Blue, White, Far-Red)
Reproduce independent multi-spectrum control for research or dynamic commercial crops
Support end-of-day far-red treatments and crop morphology strategies without light loss
Heliospectra product documentation indicates that the MITRA X platform offers modular configurations from 325W to 1500W with nominal photon efficacy up to 3.7 μmol/J. The C3 platform incorporates three adjustable channels; the C4 platform provides four independent spectral channels; and the FLEX platform supplies three switchable spectral modes. Matching these parameters requires clear technical alignment.
MITRA X Fixed-Spectrum Alternatives
The MITRA X series serves as a high-output fixed-spectrum top light for commercial greenhouse production. Available in linear and split power supply configurations, it targets high-dLI vegetable crops and leafy green operations.
When replacing MITRA X fixtures, engineering evaluation focuses on matching target spectral power distribution, total PPF output, canopy distribution, and mounting footprint. Operators must decide whether to replace individual failed units within an existing zone or re-simulate the optical layout for an entire bay using updated high-efficacy fixtures.
The MITRA X C3 is not a static single-channel fixture. It features three independently controllable spectral channels: a broad base spectrum, a horti-white channel, and a far-red channel. This allows growers to adjust light quality between vegetative and fruiting growth stages.
Replacing a C3 fixture requires defining the peak wavelength, power distribution, and photon output of each channel. Facilities must determine whether independent 3-channel dimming is strictly necessary for ongoing crop steering or if a optimized dual-channel or customized fixed spectrum can achieve equivalent yield outcomes.
The MITRA X C4 is designed for high-precision dynamic lighting, featuring four independently adjustable channels: Red (660nm), Blue (450nm), White, and Far-Red (730nm). It is frequently deployed in research institutions, speed breeding facilities, and specialized commercial greenhouses.
A C4 replacement cannot be evaluated on total micromoles alone. Each individual color channel must be mapped to ensure the target spectral ratios, peak intensity, and dimming ranges are preserved. FY LIGHTING develops custom multi-channel LED drivers and light engines tailored to match these specific multi-spectrum requirements following prototype validation.
The MITRA X FLEX delivers three distinct spectrum modes within a single fixture: broad spectrum, broad spectrum plus far-red, and far-red only. Its primary commercial applications include end-of-day (EOD) far-red lighting, photoperiod manipulation, extension lighting, and crop morphology control.
When replacing FLEX units, far-red photon output (700–800 nm ePPF) and spectral wavebands must be verified. Simply adding standard 735nm LEDs is insufficient; the far-red to red photon ratio, beam spread, and thermal dissipation must align with crop development targets.
Understanding the technical distinction between a Performance Replacement and a Physical Retrofit Replacement helps greenhouse operators set realistic project timelines and installation budgets.
Dimensions & Weight: Overall fixture length, width, height, and total weight.
Form Factor: Linear bar, modular split-PSU, or compact square footprint.
Mounting Structures: Compatibility with greenhouse unistrut, C-brackets, or pipe-rail hangers.
Ingress Protection: IP65 or IP66 rating for dust resistance and high-pressure water washdown.
Shading Footprint: Slim mechanical profile to minimize shadow impacts under natural sunlight.
Control Requirements
Control Channels: Single-channel fixed, 3-channel, or 4-channel dynamic dimming.
Communication Protocol: Wired 0–10V/DALI or wireless protocols.
Zoning & Scheduling: Ability to group fixtures into independent lighting zones and automated photoperiod schedules.
Spectrum, PPF, PPE and PPFD Matching
When evaluating replacement grow lights, technical terms must be accurately distinguished:
Spectrum: The specific mixture of light wavelengths (blue, green, red, far-red) produced by the LEDs.
PPF (Photosynthetic Photon Flux): The total amount of PAR light emitted by the light fixture per second, measured in μmol/s.
PPE (Photosynthetic Photon Efficacy): How efficiently the fixture converts electrical energy into PAR photons, measured in μmol/J.
PPFD (Photosynthetic Photon Flux Density): The actual intensity of photons reaching a specific square meter of crop canopy per second, measured in μmol/m²/s.
Equal PPE does not mean equal PPF: Two fixtures rated at 3.2 μmol/J will produce different total light output if their input wattages differ (e.g., 325W vs 650W).
Equal PPF does not mean equal canopy PPFD: Beam angle and reflector design alter light distribution. A narrow-beam fixture may yield high center PPFD but poor edge uniformity compared to a wide-beam fixture.
Equal PPFD does not mean identical plant response: Delivering 250 μmol/m²/s under a high-red spectrum produces different morphological results than delivering 250 μmol/m²/s under a broad-white spectrum.
Fixture Size, Mounting and Connector Compatibility
Achieving mechanical and electrical compatibility requires verifying physical details prior to manufacturing.
Fixture Footprint: Confirm length, width, and height to ensure fixtures fit beneath existing unistrut without blocking thermal dissipation or venting.
Mounting Point Spacing: Measure center-to-center distances of mounting holes or C-brackets.
Weight & Truss Loading: Ensure replacement units do not exceed the structural weight capacities of greenhouse roof trusses.
Power Cord Exit & Length: Verify power cable exit orientation and length to reach existing electrical junction boxes.
Connector Specifications: Confirm connector manufacturer, thread pitch, contact pin count, and wiring color codes.
Shading Profile: Ensure the fixture housing does not cause unnecessary shading of natural sunlight.
Technical Risk Warning: Photographs alone are insufficient to confirm mechanical or electrical compatibility. Operators should provide engineering drawings, nameplate photos, or physical samples for technical review.
Dimming and Control System Migration
Installed Heliospectra systems often utilize specialized control architectures, including ADELPHI wireless hardware and helioCORE management software.
When replacing these fixtures, facilities must plan their control migration strategy:
Legacy Platform Compatibility: Direct software integration with helioCORE cannot be assumed and must be evaluated on a project-by-project basis.
Wired 0–10V / DALI Control: Many commercial operators transition to standardized 0–10V or DALI wired dimming networks, which offer high reliability and resistance to greenhouse radio frequency interference.
Multi-Channel Drivers: Replacing multi-channel C3 or C4 fixtures requires multi-channel LED drivers capable of receiving independent control signals per waveband.
Phased System Migration: Facilities can replace fixtures zone-by-zone, maintaining legacy control on existing sections while establishing standardized control networks on new replacement bays.
Operational Boundary: Compatibility with existing Heliospectra controls must be evaluated on a project-by-project basis.
