Indoorled Master COB: The Game-Changing COB LED Lighting

Indoorled's Master COB brings Chip On Board (COB) technology to horticultural lighting. Unlike traditional LEDs that use individual diodes, the Master COB concentrates multiple LED chips on a single substrate to create an ultra-dense and homogeneous light source. The result? Exceptional light penetration and perfect distribution across the entire canopy.

Why choose Indoorled Master COB technology

The Master COB revolutionizes indoor lighting with its impressive photonic density. With a PPFD that can reach 1500 µmol/m²/s at 30cm, it significantly outperforms traditional LED panels. COB technology eliminates the shadow areas typical of multi-diode lighting and provides uniform coverage even at the edges of the growing area.

The energy efficiency of the Master COB is remarkable: it consumes 30% less than an equivalent HPS while producing less heat. No more temperature problems in small setups! The full spectrum integrates wavelengths from 380nm to 780nm, optimized for all growth phases. High-quality COBs guarantee a minimum lifespan of 50,000 hours.

How to choose your Indoorled Master COB

The choice of power depends directly on your growing area. For a 60x60cm tent, a 100W Master COB is more than sufficient. 120x120cm spaces typically require 200W to 300W depending on the available height. Hanging distance plays a crucial role: the further you can move the lamp away, the more homogeneous the distribution will be.

Check compatibility with your ventilation system. Master COBs generate concentrated heat that must be efficiently evacuated. An extractor adapted to the volume of your space (calculation: volume x 60 for the minimum flow rate in m³/h) is essential. Some models include passive heatsinks, while others require active ventilation.

The beam angle directly influences coverage. 90° COBs are suitable for low setups (less than 80cm in height), while 120° are perfect for tall tents where you can move the light further away. Also consider dimming options: an integrated dimmer allows you to adapt the intensity according to the growth phases.

Frequently asked questions

What wattage Master COB Indoorled should I choose for a 120x120cm tent?

For a 120x120cm tent (1.44m²), count on 200W to 300W depending on your goals. A 250W Master COB placed at 50-60cm height offers an optimal PPFD of 800-1000 µmol/m²/s over the entire surface. If you are growing light-hungry varieties or aiming for maximum yields, opt for 300W. For more classic crops, 200W is largely sufficient and will save you on your electricity bill.

How to adjust the height and intensity of the Master COB to avoid light stress?

Always start by placing your Master COB at a minimum of 80cm during the first few weeks, then gradually bring it closer. During vegetative growth, 60-70cm with 60-70% intensity avoids stress. During flowering, lower it to 40-50cm with 100% intensity. Watch for signs: bleaching leaves, browning edges, or stunted growth indicate excessive light. A lux meter or PAR meter will give you precise measurements for fine-tuning.

Is the Indoorled Master COB better than classic LED or HPS for indoor growing?

The Master COB surpasses classic LEDs in light penetration and homogeneity, but costs more upfront. Compared to HPS, it consumes 40% less, heats up much less, and lasts 5 times longer. The optimized spectrum of the COB promotes resin production and bud density. The only drawback: the higher initial investment, but the electricity savings and durability quickly compensate.

How to install the Indoorled Master COB in a Probox Master, with or without a reflector?

In a Probox Master, attach the Master COB directly to the suspension bars with the provided hooks. No reflector is needed: COB technology already diffuses light perfectly. A reflector can even create hot spots and reduce efficiency. Make sure to leave a minimum of 15cm between the COB and the walls for air circulation. The ideal is to perfectly center the lighting for uniform coverage over the entire growing area.

Should the COBs of the Indoorled Master COB be cleaned and how to make it last a long time?

Clean the COBs every 2-3 months with a slightly damp microfiber cloth, with the lamp off and cooled. Avoid chemical products that could damage the LED chips. Dust reduces light efficiency by 10-15% in a few months. To maximize lifespan, maintain an ambient temperature below 30°C and ensure that the ventilation effectively evacuates heat from the heatsink. A well-maintained Master COB retains 90% of its power after 30,000 hours of use.
