Sanlight Series FLEX: The Modular LED Lighting Revolutionizing Indoor Cultivation

The Sanlight Series FLEX represents a completely new approach to horticultural lighting. These modular LED bars offer unparalleled flexibility to adapt your lighting to any growing setup. Whether for multi-layer systems, vertical farms, or atypical spaces, the FLEX Series fits where traditional panels fall short.

Why Choose the Sanlight Series FLEX?

The true strength of the FLEX Series lies in its modularity. Unlike fixed LED panels, these bars can be placed exactly where you need them. Growing in multi-layers? Slide the FLEX II directly between your tiers. Do you have plants of different heights? Adjust each bar independently. This flexibility completely changes the game for maximizing your yield per square meter.

The full spectrum from 400 to 700 nm faithfully reproduces natural light. With an energy efficiency of 2.9 µmol/J, you get more photons per watt consumed. Samsung LM301H diodes guarantee a minimum lifespan of 50,000 hours. Frankly, this is equipment built to last.

Another major advantage is thermal management. FLEX II bars generate very little heat thanks to their slim design and passive dissipation. You can place them 15-20 cm from plants without risk of heat stress. This opens up enormous possibilities for optimizing vertical space.

How to Choose Your Sanlight Series FLEX Configuration

The choice primarily depends on your growing area and cultivation type. For classic multi-layers, plan for one FLEX II 25W bar every 30-40 cm. On a 60x60 cm surface, 4 FLEX II 25W bars provide homogeneous coverage with an average of approximately 400 µmol/m²/s.

The length of the bars also plays a role. FLEX II are available in 25W, 35W, and 50W with lengths of 56 cm, 78 cm, and 112 cm respectively. For narrow spaces or vertical systems, the 25W are perfect. For covering larger areas at once, the 50W are more efficient.

Regarding power supply, a single driver can power multiple FLEX II bars. The 100W driver can manage up to 4 x 25W bars or 2 x 50W bars. This is convenient for simplifying installation and reducing cables. Just remember to check the total power to avoid overloading.

For intensity, the FLEX Series is dimmable from 10 to 100%. Always start low with young plants: 30-40% is more than enough for seedlings and cuttings. You will gradually increase it according to the development stage.

Frequently Asked Questions

Which Sanlight FLEX II length should I choose for my multi-layer indoor growing system?

For multi-layers, opt for the FLEX II 25W (56 cm) or 35W (78 cm) depending on the width of your shelves. The 25W are perfect for 60 cm wide shelves, while the 35W better cover 80 cm shelves. The idea is to have one bar every 30-40 cm for homogeneous distribution. The 50W (112 cm) are more suitable for large areas than for multi-layer systems where vertical space is limited.

Can FLEX II be placed directly between plants without risk of burning?

Yes, that's precisely the advantage of FLEX II. Thanks to their low heat emission, you can place them 15-20 cm from plants without stress. Their slim design and passive dissipation maintain a very reasonable surface temperature. Be careful not to go below 10 cm, especially at full power. Start at 20 cm and adjust according to your plants' reaction.

What light intensity should I use with FLEX II 25 for seedlings?

For seedlings, stay between 30 and 50% of the maximum power of the FLEX II 25W. This provides approximately 100-150 µmol/m²/s, which is largely sufficient for this phase. Place the bars 25-30 cm from the seedlings and observe carefully: if the internodes remain short and the leaves are green, you're good. If you see signs of stress (curling leaves), lower the intensity or move the bars a little further away.

How do I connect multiple FLEX II to a single LED driver?

FLEX II connect in series to the same driver using their special connectors. A 100W driver can power up to 4 x 25W bars or a maximum of 2 x 50W bars. Use the provided connecting cables to link the bars together, then connect the first bar to the driver. Always ensure that the total power does not exceed that of the driver. The system is plug-and-play, no soldering or DIY required.

What is the minimum distance to maintain between FLEX II and plants?

The recommended minimum distance is 10 cm, but 15-20 cm is safer to avoid any risk. This distance varies depending on the intensity used and the plant stage. For fragile seedlings, keep 25-30 cm even at low intensity. During active growth, 15-20 cm at 70-80% power works very well. During flowering, you can go down to 12-15 cm if your plants tolerate it well. The important thing is to observe and adjust gradually.
