HortiBloom Mega Optic 800W LED Grow Light

The HortiBloom Mega Optic 800W LED Grow Light is a high-output, full-spectrum horticultural fixture engineered for grow tents, indoor rooms, benches, and commercial production environments. Producing 2,560 µmol/s of PPF at an efficacy of 3.2 µmol/J, it delivers intense plant-usable light across a 5' × 5' flowering footprint while drawing 800 watts at full power.

The defining feature of the Mega Optic platform is its custom secondary optical lens system. Rather than relying exclusively on broad, unfocused diode output, the specialized lenses direct usable photons deeper through the canopy. This improves illumination through the middle and lower portions of the crop while maintaining consistent PPFD across the intended growing area.

The Mega Optic 800W uses 3,600 Samsung LM281B+ Pro white diodes combined with Osram blue, red, deep-red, and far-red LEDs. Its optimized full-spectrum output supports propagation, vegetative development, and flowering, allowing the same fixture to remain in service throughout the complete growing cycle.

With a flowering footprint of approximately 5' × 5' and vegetative coverage up to 7' × 7', the fixture provides broad coverage without requiring an oversized installation. Actual performance will vary with hanging height, dimming level, canopy density, environmental conditions, and room reflectivity.

The fixture is positioned as an efficient replacement for approximately an 1100W HPS or MH system. Its 800W input reduces electrical demand while the optical platform maintains strong intensity and deeper canopy penetration.

An integrated 0–100% dimmer knob allows operators to match output to plant development and environmental conditions. The fixture also includes a 0–10V RJ control port for integration with compatible lighting controllers and centralized production systems.

The low-profile aluminum fixture measures only 1.6 inches thick, preserving valuable overhead clearance in tents and low-ceiling rooms. Passive thermal management dissipates heat without fans, reducing noise and eliminating moving cooling components that require routine service.

Its IP65 rating supports operation in damp indoor horticultural environments, while the UL-listed driver is designed for dependable long-term performance. The Mega Optic manual recommends regular lens cleaning, inspection of hangers and cables, and annual checks of electrical connections and heat sinks.

Backed by a 5-Year Limited Manufacturer Warranty, the HortiBloom Mega Optic 800W is built for growers who need high photon output, full-spectrum performance, deep canopy penetration, and precise intensity control.

Custom Secondary Optical Lenses

The Mega Optic 800W uses purpose-built secondary lenses engineered specifically for horticultural lighting.

These optics direct more usable light through the canopy, improving illumination across middle and lower growth compared with conventional open-diode fixtures.

2,560 µmol/s PPF Output

The fixture produces 2,560 µmol/s of photosynthetic photon flux.

This high-output platform provides the intensity required for demanding indoor horticultural applications while maintaining an 800W electrical load.

3.2 µmol/J Fixture Efficacy

With efficacy reaching 3.2 µmol/J, the Mega Optic 800W converts electrical power into plant-usable light efficiently.

Higher efficacy supports strong canopy intensity while limiting unnecessary electricity consumption and heat generation.

Samsung & Osram Diodes

The fixture combines Samsung LM281B+ Pro white LEDs with Osram blue, red, deep-red, and far-red diodes.

This premium diode arrangement creates a broad, balanced spectrum for full-cycle plant development.

Full-Spectrum Output

The Mega Optic spectrum supports propagation, vegetative growth, and flowering.

Operators can use one fixture throughout the complete growing cycle without switching between stage-specific lighting systems.

5' × 5' Flowering Coverage

The Mega Optic 800W is designed for approximately 5' × 5' flowering coverage.

Its square fixture layout and optical lenses help maintain consistent PPFD across the center, edges, and corners of the canopy.

Up to 7' × 7' Vegetative Coverage

At lower intensity and greater hanging height, the fixture can support vegetative areas up to approximately 7' × 7'.

This broader footprint provides flexibility for early-stage production and larger vegetative rooms.

Deep Canopy Penetration

HortiBloom’s optical platform is engineered to direct photosynthetic light deeper through dense plant structures.

The manufacturer states that Mega Optic fixtures can provide effective light penetration at depths reaching approximately 4 feet, depending on canopy conditions and installation.

1100W HID Replacement

The Mega Optic 800W is designed as an efficient alternative to approximately an 1100W HPS or MH fixture.

Its lower input power can reduce electrical and cooling requirements while preserving high photon output.

0–100% Manual Dimming

An integrated dimmer knob provides continuous output adjustment from 0% to 100%.

Intensity can be reduced during early growth and increased gradually as plant requirements change.

0–10V Smart Control

The built-in 0–10V RJ port supports compatible external lighting controllers.

This allows centralized dimming, grouped fixture management, and automated lighting schedules in larger installations.

90° Beam Angle

The custom optical system produces a focused 90-degree beam angle.

This helps direct output efficiently across the canopy while supporting stronger penetration than wider, unfocused light distributions.

Passive Thermal Management

The aluminum fixture dissipates heat through natural convection without internal cooling fans.

Passive operation reduces noise, minimizes maintenance, and supports stable long-term diode performance.

Low-Profile Aluminum Frame

Measuring only 1.6 inches thick, the Mega Optic 800W preserves overhead clearance in grow tents, compact rooms, and low-ceiling installations.

Its broad 42.8-inch square frame distributes output across the canopy without excessive vertical bulk.

IP65-Rated Protection

The fixture carries an IP65 rating for damp indoor horticultural environments.

It should still be protected from direct water spray, standing water, and outdoor exposure.

Replaceable Optical Lenses

The optical lenses can be cleaned as part of routine maintenance and replaced if damaged.

The manufacturer notes that each light strip incorporates three independent lens sections, supporting more targeted servicing.

5-Year Manufacturer Warranty

The HortiBloom Mega Optic 800W is backed by a 5-Year Limited Manufacturer Warranty covering qualifying defects under normal operating conditions.

The manufacturer recommends monthly lens cleaning and annual inspection of electrical connections and heat sinks.
