The PFS 40W is a unique option coming from the PFS series. It provides a more balanced full phase spectrum ensuring better indoor growth and efficiency. The PFS40W LEDs are remarkably thin with only 1.5-inch width.

It’s a 47.2” x 5.1” design, so the pack of 4 lights is a great option for any 4’x’4 or bigger growing tents. Designed to work in denser farming environments, it outputs up to 2.5 umol/J.

It's a low-profile LED, ideal for leafy greens, herbs, and ornamental crops. So, it's preferable for seeding and cloning beds due to its minimal photon flux density. Also, it serves as an easy substitute for fluorescent lamps because of its size, weight, and easy installation. On top of that, it can relieve up to 60% of HVAC and electricity bills.

A balanced spectrum means that it can cover beyond the 660nm wavelengths too. Moreover, the light color is also realistic, providing natural growth environments to the plants.

It's just a 40-Watt light weighing approximately one kg. So, you can mount it anywhere above 6 inches, and it will provide a reliable 120-degree light distribution. Compact, efficient, and durable, the PFS40W can easily be your next professional LED grow light.


Balanced spectrum, Incorporating Grower’s Choice famous 3K CMH Full Phase Spectrum for superior growing power with best possible LED diodes available.

Energy Saving & Easy HVAC:

Up to 60% energy savings. 60% less HVAC requirement.

Full Spectrum

The specially deployed full spectrum fills the negligence of the main photoreceptors and pigments outside the 660nm and 450nm range, and it is suitable for reproduction to aging in indoor environments. The overall color temperature of FSM's full spectrum is controlled at 3000-3300K, which increases the radiant energy of red light at 660nm wavelength in white light. It provides a beautiful working environment and a more realistic color reproduction degree at a CRI level of 85.

PPF Calculations:

PPF calculations complied using our in-house integrating sphere measurements & typical spectroradiometer data for each LED to determine the fixture performance. Actual photometric results may vary within the LED’s manufacturer’s bin tolerance.

Wattage Values:

Wattage values are typical expected values. TSL Horti Tech maintains a tolerance of +/- 10% range on flux & power consumption. Target light level can vary from projected levels depending on ambient temperature, room reflections values, & other conditions.
