Secret Jardin Tled 42 Watt Bloom
The Secret Jardin TLED 42W Bloom is a 95 cm LED bar — nearly twice the length of the 26W variant — engineered for larger flowering-phase coverage. Rated at 42W delivering approximately 3000 lumens at 80 lm/W efficacy, it directly illuminates 100x20 cm or functions as significant supplemental lighting in grow tents up to 1.5 m². Spectral output combines infrared 730 nm, 2100K, and 3000K diodes for the red-dominant spectrum flowering requires. Low thermal output allows mounting at just 20-30 cm from the canopy without foliar burn — a proximity unavailable with HPS fixtures. Universal 110-220V input with no external driver, including suspension clips for horizontal or vertical tent-pole mounting.
Secret Jardin TLED 42W Bloom — 95 cm LED Bar for Medium-Scale Flowering Deployments
The Secret Jardin TLED 42W Bloom represents the upper tier of Secret Jardin's flowering TLED range. While the 23W variant serves primarily as vertical supplemental lighting in larger tents, the 42W positions itself as a primary illumination option for compact installations or substantial supplementation in spaces up to 1.5 m². The 95 cm form factor distributes photonic output across a significantly wider footprint while preserving the thermal advantages that define LED technology versus HPS alternatives.
Photon Output and Spectral Distribution
The 42W bar houses proportionally more diodes than the smaller sibling, organized into the same three spectral families: infrared 730 nm triggering the Emerson effect, warm white 2100K providing dominant red output, and warm white 3000K extending PAR coverage into mid-spectrum wavelengths. Total luminous flux reaches approximately 3000 lumens at 80 lm/W efficacy. The 120° beam angle delivers uniform illumination across the target footprint without the hotspot phenomena typical of point-source fixtures — a practical advantage when mounting at minimum canopy distances.
- Dimensions 95x4x3 cm, weight 0.58 kg: nearly double the 26W length but retaining the slim profile compatible with standard tent suspension systems.
- Voltage range 110-220V at 50/60 Hz: universal compatibility across European and most international grid standards without adapters.
- Integrated driver electronics: plug-and-play direct-connection via the supplied 240 cm IEC cable.
- 30,000-hour MTBF rating: equivalent to approximately 6.8 years of flowering-cycle operation at 12 hours daily.
- Suspension hardware included: mounting clips support both ceiling suspension and vertical attachment to tent poles up to 30 mm diameter.
Deployment Scenarios Based on Tent Architecture
Optimal use of the 42W depends on installation scale. In compact tents of 80x80 cm or 100x100 cm with moderate plant density, a single bar can function as primary flowering illumination — insufficient to replace a 250W HPS in raw PAR delivery, but adequate for autoflower cycles or limited cola counts. In larger tents of 120x120 cm and beyond, the 42W excels as vertical supplemental lighting mounted along tent walls, targeting the lower canopy strata that ceiling-mounted primary fixtures reach inefficiently. Field yield data documents 15-25% harvest improvements when TLED supplementation is added to central HPS configurations in larger tents.
System Integration and Spectrum Coverage
For a complete cultivation cycle within the Secret Jardin ecosystem, pair this flowering bar with the TNOLED 2x40W Grow providing the cool-spectrum output required during vegetative growth. Alternating between these fixtures aligns spectral delivery with each phenological stage. For growers preferring a single-fixture full-cycle solution, the Cosmorrow 40W Grow offers broader spectrum coverage. In commercial-scale deployments, TLED bars typically complement a primary HPS or LED panel rather than operating in isolation — the technologies fulfill different roles within an integrated lighting architecture.

How does the 42W compare to the 26W in terms of PAR coverage per unit cost?
The 42W delivers approximately 50% more lumens at 61% more wattage, so watt-for-watt the efficiency is marginally lower than the 26W. However, the 42W covers significantly more linear canopy surface (100x20 cm versus 60x40 cm effective footprint) which often translates to better economics for installations where single-bar coverage is sufficient. For supplemental applications in large tents, stacking multiple 26W bars can deliver more distributed light than fewer 42W units at similar total wattage.
What photoperiod timer should I use with TLED 42W bars?
Standard mechanical or digital grow timers rated for 10A at 230V handle multiple TLED bars without capacity concerns — each bar draws approximately 0.2A. For flowering cycles, a precise 12/12 timer is critical: any exposure to light during the dark phase can disrupt flowering hormones and delay bud development. Opt for timers with battery backup to preserve schedules during brief power interruptions. Cheap mechanical timers with 15-minute minimum granularity work adequately for 12/12 schedules.
Can the TLED 42W be used with greenhouse cultivation or only indoor tents?
The IP rating for this fixture is not specified for full weather exposure, making it unsuitable for direct outdoor use. However, inside a greenhouse environment with standard ambient humidity (below 80% RH sustained), the bars operate reliably as supplemental lighting — particularly valuable during shoulder seasons when natural photoperiod duration is insufficient for flowering triggers. Protect the IEC connection from condensation with standard cable management practices.
Does the LED output degrade measurably over the 30,000-hour service life?
Quality LED fixtures like the TLED maintain 70-80% of initial output at the end of rated life (L70 lifespan metric). This gradual degradation is typically imperceptible to growers during normal cycle operation but measurable with PAR meters. For performance-critical commercial operations, some growers replace fixtures at 15,000-20,000 hours rather than waiting for full end-of-life to maintain peak yield performance. For hobbyist cultivation, running fixtures to full MTBF remains economically rational.
