Bell Howell Grow Burst

Grow Burst is a full‑spectrum LED module that mimics natural sunlight while delivering targeted wavelengths that stimulate photosynthesis. Unlike generic grow lights, it incorporates a proprietary pulse‑width modulation (PWM) algorithm that creates brief, high‑intensity bursts of light, hence the name “Burst.” These bursts trigger a physiological response in plants, encouraging faster leaf expansion and stronger root development.

The system operates on two scientific concepts: photomorphogenesis and photosynthetic efficiency. By delivering light in rapid, high‑peak pulses, the LEDs stimulate chlorophyll molecules more effectively than continuous illumination. This approach reduces heat output, conserves power, and aligns with the plant’s natural diurnal rhythms.

Grow Burst is versatile enough for leafy greens, herbs, microgreens, and even early‑stage fruiting plants. During the vegetative stage, you’ll use a balanced spectrum (400‑700 nm) to promote foliage. In the flowering stage, the device can be switched to a red‑heavy spectrum (620‑660 nm) to support bud formation and fruit set.

The heart of Grow Burst is a matrix of high‑efficiency diodes arranged in a hexagonal pattern. Each diode is rated at 3 W and can be individually dimmed. The array includes:

• Cool‑white LEDs (400‑500 nm) for blue light
• Full‑spectrum white LEDs (500‑600 nm)
• Deep‑red LEDs (660 nm) for flowering

The built‑in PWM controller modulates the duty cycle at frequencies up to 5 kHz. This rapid on/off switching creates the “burst” effect without noticeable flicker to the human eye. Users can adjust the burst duration (10‑100 ms) and interval (1‑30 seconds) via the touchscreen interface.

Grow Burst integrates Wi‑Fi and Bluetooth, allowing remote monitoring through the Bell Howell app. Built‑in sensors track ambient temperature, humidity, and light intensity, feeding data to an AI‑driven optimizer that suggests real‑time adjustments for optimal growth.

Studies show that the burst methodology can cut vegetative growth time by up to 25 %. The high‑peak photons boost chlorophyll activity, leading to faster leaf emergence and earlier harvest dates, which is especially valuable for commercial growers on tight production schedules.

Because the LEDs operate in short bursts, the average power draw is 30‑40 % lower than continuous‑wave grow lights. Over a typical 12‑hour photoperiod, this translates to an annual electricity saving of roughly $200‑$300 per unit, depending on local rates.

Plants exposed to burst lighting exhibit higher chlorophyll content, deeper green coloration, and stronger stems. For leafy greens, this means a crisper texture and better post‑harvest shelf life, while fruiting crops often show increased sugar accumulation and uniform ripening.

Begin by laying out all parts: the LED panel, mounting brackets, power cable, and user manual. Verify that the model number matches your purchase order and inspect the LEDs for any visible damage. Use the checklist in the manual to confirm you have:

• Panel
• Two steel brackets
• Adjustable hanging kit
• Power adapter (120 V AC)

Secure the brackets to the ceiling or grow‑tent frame using the supplied M6 screws. Position the panel at a height of 30‑45 cm above the canopy for leafy greens, or 45‑60 cm for taller plants. Tighten all fasteners evenly to avoid vibration, which could affect the PWM timing.

Plug the power cord into a grounded outlet and press the power button on the rear panel. The LED indicator will flash green, indicating it’s awaiting network configuration. Open the Bell Howell app, select “Add Device,” and follow the on‑screen prompts to connect via Wi‑Fi. Once paired, you can name the unit (e.g., “Veg‑Tent‑A”).

For most vegetables, a 16‑hour light / 8‑hour dark cycle yields the best balance of growth and energy use. Use the app’s schedule tab to set start and end times, and enable the “Sunrise/Sunset” simulation for a gradual ramp‑up and ramp‑down, which reduces plant stress.

Start with the factory default: 50 ms burst duration every 10 seconds. If you notice leaf scorching, increase the interval to 20 seconds or lower the burst duration to 30 ms. Conversely, for slow‑growing varieties, you can shorten the interval to 5 seconds for a modest boost in photon flux.

Sync Grow Burst with your climate controller (HVAC, CO₂, humidifier). The app can receive sensor data and automatically adjust burst intensity when temperature exceeds 28 °C or humidity drops below 40 %. This synergy ensures plants receive optimal light without overheating.

If you observe irregular flicker, first check the power connection for loose plugs. Next, verify that the firmware is up‑to‑date via the app’s “System Update” menu. Persistent issues may indicate a faulty PWM controller; contact Bell Howell support with the serial number for a replacement.

Although Burst mode reduces heat, improper spacing can cause temperature buildup. Ensure at least 10 cm clearance around the panel and clean the built‑in heat‑sink fins quarterly. If the internal temperature sensor reads above 65 °C, the system will auto‑shutdown—reset after allowing a 10‑minute cool‑down.

Wi‑Fi interference from nearby routers can cause intermittent loss of control. Relocate the unit to a spot with a strong signal, or switch to the 5 GHz band in the app’s network settings. For persistent problems, consider using a dedicated Wi‑Fi extender positioned between the router and grow area.

Always power off the unit before performing any maintenance. Use a grounded outlet and avoid daisy‑chaining multiple Grow Burst units onto a single power strip exceeding 15 A. Keep the power cable away from water sources and never expose the panel to direct spray.

Dust can diminish light output. Gently wipe the panel with a soft, lint‑free cloth slightly dampened with distilled water. Avoid abrasive cleaners or solvents, which can damage the protective coating. Perform this routine monthly, or more often in dusty environments.

Bell Howell releases firmware upgrades quarterly to improve burst algorithms and add new plant‑specific presets. Enable “Automatic Update” in the app, or manually check the “System” tab. Keeping the software current ensures you benefit from the latest efficiency gains and bug fixes.

Grow Burst is designed to complement, not necessarily replace, existing lighting. For small‑scale setups, a single unit may suffice, but larger commercial operations often pair Burst panels with high‑output HPS or LED fixtures to achieve uniform coverage across extensive canopies.

Bell Howell offers a **2‑year limited warranty** covering manufacturing defects on the LED array, housing, and controller. The warranty is void if the unit is modified, exposed to water, or used with non‑approved power sources. Register your product online within 30 days to activate coverage.

Support is available via the Bell Howell website, where you can submit a ticket, download the full user manual, and access a library of video tutorials. Phone support (1‑800‑555‑GROW) is open Monday‑Friday, 9 am‑5 pm EST. For quick answers, the community forum hosts discussions from experienced growers worldwide.
