SOLUX Super HPS 400W Bulb

SOLUX Super HPS 400W Bulb

The SOLUX 400W Super HPS bulb prioritizes red and orange wavelengths that activate flowering processes, promoting dry weight , resin production , and uniform ripening. The 400W format offers an ideal balance between light penetration and heat control in 80–120cm grow tents or medium-sized rooms.

The warm 2000K color temperature reduces late stretch and helps fill in mid-layers, while the E40 socket allows the lamp to be integrated into standard reflectors with 400W magnetic or electronic ballasts . A flux of 49,000 lumens distributed with a good reflector creates a homogeneous wash over low-profile SOG or well-stretched SCROG nets, limiting shadows and improving layer uniformity.

The stated lifespan is around 24,000 hours ; a simple log of hours and periodic cleaning of the reflector help to maintain performance.

In modern strategies, it is common to enhance the perimeter area with low-power LED grow lights , obtaining extra coverage without excessively increasing the thermal load of the central HPS point.

The bulb works especially well combined with HM/CMH or cool LED during growth, building a compact vegetative base that allows you to take advantage of the warm intensity of the final stage.

For a stable environment, it's advisable to adjust extraction, oscillating ventilation, and photoperiod, while maintaining leaf temperature and VPD within range. All of this results in compact colas, well-defined pistils, and consistent aromatic profiles in cannabis cultivation .

Indoor Growing Super HPS 400W Bulb SOLUX

Designed for indoor growing in medium-sized spaces, this lamp excels in 80x80, 100x100, or 120x120 cm grow tents. Its warm light penetrates dense canopies with ease, accelerating growth. With a properly sized extraction system and fans circulating air between the canopies, the microclimate remains stable, maximizing yields per square meter without excessive heat.

What is the SOLUX 400W Super HPS Bulb used for?

It promotes abundant and uniform flowering . The emphasis on red tones encourages fruit fattening , density, and simultaneous maturation—key elements for an attractive commercial result. In medium-sized cannabis plants , it helps consolidate production with controlled consumption, ideal for tight work schedules and continuous crop rotations.

How do I use the SOLUX 400W Super HPS Bulb?

1. Disconnect the power and allow to cool completely before handling. Screw the lamp into an E40 socket, holding it by the base.
2. Connect to verified 400W ballast ; check grounding, fuses and wiring gauge.
3. Program a 12/12 photoperiod for flowering; maintain extraction and oscillating ventilation to stabilize the climate.
4. Start 45–60 cm away from the canopy; gradually approach, monitoring leaf temperature and avoiding hot spots.
5. Clean the reflector periodically, check connections, and note the installation date to plan for preventative replacement in case of lumen drop.
6. In hybrid schemes, add LED bars at the edges to increase uniformity without excessively increasing the central thermal load.
