2026 ProTerp 600W LED Grow Light – 3.13 PPE/3.2 ePPE CMH Full Spectrum

But spectrum determines how those photons are used.

A plant receiving high intensity under an incomplete spectrum will not perform the same as one receiving balanced spectral input.

The ProTerp was designed to deliver broad-spectrum energy across blue, green, red, and far red wavelengths to create a lighting environment that behaves more like natural daylight than conventional narrow-band horticultural fixtures.

The objective isn’t simply more photons.

It’s delivering the right photons in the right proportions.

🔵 Triple Blue Platform

437nm + 450nm + Dedicated 480nm Cyan (triple Blue)

Designed to support tighter morphology, signaling behavior, structural development, and balanced growth under high-intensity environments.

🟢 Emerald Green Mid-Band

525nm Green improves whole-canopy activation and deeper penetration into dense flowering environments.

🔴 Dual Red Architecture

Rather than oversaturating the fixture with red to chase efficacy numbers, the ProTerp uses controlled red balancing.

By smoothing the natural reduction between 600–640nm, the fixture improves spectral continuity and photon efficiency while intentionally keeping total red below 40%.

The goal isn’t exaggerated red loading.

The goal is a smoother spectral curve.

🌸 Independently Dimmable 730nm Far Red

Far red should be adjustable, not permanently forced into the fixture.

The dedicated dimmable 730nm channel allows growers to introduce additional far red only when desired for crop steering and morphology management.

With the independently dimmable 730nm far-red channel disabled, the fixture operates as a high-efficiency CMH / Sunlike spectrum delivering 1908 µmol/s PPF and 1931.2 µmol/s ePPF at 3.131 PPE and 3.17 ePPE. Enabling the independently dimmable far-red channel increases total output to 1919 µmol/s PPF and 2029.6 µmol/s ePPF, while adding 109.7 µmol/s of dedicated far-red photon flux for crop steering, canopy management, and end-of-cycle finishing without permanently altering the baseline CMH / Sunlike spectrum.

It combines the full CMH / Sunlike multi-peak platform with controlled dual red output and an independently dimmable 730nm far-red channel.

The dual-red architecture fills the natural dip between 600–640nm with controlled 640nm output alongside the dominant 660nm peak, smoothing the red region of the spectrum and delivering improved photon efficiency without pushing the fixture into exaggerated red-heavy territory.

The independently dimmable 730nm channel allows growers to selectively introduce far red when and where it is beneficial.

With far red fully disengaged, the fixture operates as a balanced dual-red CMH / Sunlike profile.

With far red enabled, growers gain an additional tool for managing structure, canopy development, crop steering, and end-of-cycle behavior without permanently altering the baseline spectrum.

Vegetative & Early Flower

Introduce lower levels of far red to encourage canopy expansion and moderate internodal extension in cultivars that remain overly compact.

Mid–Late Flower

Apply far red after stretch to support uniform floral development and manage late-cycle finishing behavior.

Run it fully disabled for traditional broad-spectrum performance.

Turn it up when the environment and genetics benefit from additional steering.

Over 5 diodes per watt.

Higher diode density reduces thermal stress, improves photon uniformity, supports long-term output stability, and minimizes efficiency loss over time.

This 600W Sunlike ProTerp configuration is built around a true multi-peak sunlike spectral architecture designed to closely mirror natural sunlight and high-quality CMH-style profiles, while delivering modern LED efficiency.

The spectrum is anchored by dual blue peaks at 437nm and 450nm, a balanced cyan and green mid-band, and a controlled 660nm red peak to maintain proper plant morphology, terpene expression, and overall crop quality across full-cycle cultivation.

This configuration delivers 3.045 PPE (400–700nm) and 3.09 ePPE (380–800nm) with a measured output of 1840 µmol/s (400–700nm) and 1866 µmol/s (380–800nm) and a measured spectral distribution of approximately 25% blue, 38% green/yellow, 35% red, and 1.3% far red.

The high color rendering index (CRI 92.7%) reflects the quality and continuity of the spectrum, closely resembling natural daylight rather than the narrowband output of typical horticulture LEDs.

In real-world use, the 600W Sunlike ProTerp is ideally suited for 4×4 w/ and w/o CO2 – 5×5 w/o CO2 flowering coverage or 5×5 vegetative and auto flower coverage, providing even canopy penetration, strong structural development, and balanced spectral input for terpene and secondary metabolite production.

This configuration is designed for growers who want a true sunlike baseline spectrum without dedicated 640nm red.

As seen on the datasheet for OSRAM GH CSBRM4.24, also known as Osram 424, diodes marketed as “660nm” can have a dominant wavelength closer to 640nm, with a broader emission curve that spans much of the red region.

This is normal diode behavior and illustrates why spectrum labels alone can be misleading.

We include this level of detail as part of our ongoing effort to promote transparency and consumer education, helping growers understand what photons are actually being delivered rather than relying on marketing hype.
