HortiBloom Mega Optic 720W LED Grow Light

The HortiBloom Mega Optic 720W LED Grow Light is a high-efficiency, full-spectrum horticultural fixture designed for grow tents, indoor rooms, benches, and commercial cultivation areas. Producing 2,304 µmol/s of PPF at an efficacy of 3.2 µmol/J, it delivers strong canopy intensity while drawing only 720 watts.

Its defining feature is HortiBloom’s custom secondary optical lens system. Unlike conventional LED fixtures that rely primarily on broad diode output, the Mega Optic platform uses purpose-built lenses to direct more usable light deeper into the canopy. This helps improve illumination through the middle and lower portions of the crop while maintaining uniform PPFD across the growing area.

The fixture combines 2,700 Samsung LM281B+ Pro diodes with Osram blue, red, deep-red, and far-red diodes. This optimized full-spectrum arrangement supports propagation, vegetative development, and flowering under one fixture.

Designed for approximately 4' × 4' to 5' × 5' flowering coverage, the Mega Optic 720W can also support vegetative areas up to approximately 7' × 7', depending on hanging height, intensity, room reflectivity, and crop requirements.

The Mega Optic 720W is positioned as an efficient alternative to approximately a 1000W HPS or MH fixture. Its lower power draw can reduce electrical demand while the advanced optical system helps preserve canopy intensity and penetration.

An integrated 0–100% dimmer knob allows output to be adjusted manually as plant requirements change. A built-in 0–10V RJ control port also supports compatible external controllers for centralized intensity adjustment and automated lighting control.

Its low-profile aluminum frame measures only 1.6 inches thick, helping preserve valuable vertical space in grow tents and low-ceiling rooms. Passive thermal management removes heat without cooling fans, reducing noise and eliminating moving components that would otherwise require maintenance.

The fixture carries an IP65 rating for damp indoor horticultural environments and uses a UL-listed driver for dependable long-term operation. HortiBloom’s Mega Optic manual recommends periodic 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 720W is built for growers seeking high output, deep canopy penetration, precise dimming, and efficient full-spectrum performance.

Custom Secondary Optical Lenses

The Mega Optic 720W uses proprietary secondary lenses engineered specifically for horticultural lighting.

These optics direct more usable light through the canopy than conventional open-diode fixtures, helping improve illumination across the middle and lower portions of the growing area.

2,304 µmol/s PPF Output

The fixture produces 2,304 µmol/s of photosynthetic photon flux.

This high-output platform delivers the intensity required for demanding indoor growing applications while maintaining a manageable 720W electrical load.

3.2 µmol/J Fixture Efficacy

With efficacy reaching 3.2 µmol/J, the Mega Optic 720W converts electrical power into plant-usable light with exceptional efficiency.

Higher efficacy helps reduce wasted electricity and heat compared with older lighting technologies.

Samsung & Osram Diodes

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

This diode platform provides a balanced full-spectrum output suitable for the complete growing cycle.

Full-Spectrum Output

The Mega Optic spectrum is designed for propagation, vegetative growth, and flowering.

One fixture can remain in service throughout the entire production cycle without switching between separate stage-specific lights.

4' × 4' to 5' × 5' Flowering Coverage

The fixture is designed to cover flowering areas from approximately 4' × 4' to 5' × 5'.

Actual coverage depends on hanging height, intensity, canopy density, room reflectivity, and environmental conditions.

Up to 7' × 7' Vegetative Coverage

At lower intensity and greater hanging height, the Mega Optic 720W can support vegetative areas up to approximately 7' × 7'.

This broader footprint makes the fixture useful for early-stage plant development and larger vegetative rooms.

Deep Canopy Penetration

HortiBloom’s optical lens system is engineered to improve photon delivery through dense plant structures.

The manufacturer states that the Mega Optic platform can provide effective light penetration to depths of up to approximately 4 feet, depending on canopy conditions.

1000W HID Replacement

The Mega Optic 720W is designed as an efficient replacement for approximately a 1000W HPS or MH fixture.

It provides high photon output while reducing overall power consumption and cooling demand.

0–100% Manual Dimming

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

Operators can reduce intensity during early plant development and increase output as canopy demand rises.

0–10V Smart Control

The built-in 0–10V RJ port allows the fixture to connect with compatible external lighting controllers.

This supports group dimming, centralized intensity management, and automated production schedules.

90° Beam Angle

The fixture uses a focused 90-degree beam angle to direct light efficiently across the canopy.

This supports stronger penetration while maintaining broad, even coverage throughout the intended footprint.

Passive Thermal Management

The aluminum frame dissipates heat without fans or other moving cooling components.

Passive operation reduces noise, limits maintenance, and supports dependable long-term performance.

Low-Profile Construction

At only 1.6 inches thick, the Mega Optic 720W preserves overhead clearance in grow tents, compact rooms, and low-ceiling installations.

Its 42.8-inch square frame provides broad canopy coverage without excessive vertical bulk.

IP65-Rated Protection

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

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

5-Year Manufacturer Warranty

The HortiBloom Mega Optic 720W is backed by a 5-Year Limited Manufacturer Warranty covering qualifying defects under normal operating conditions.

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