E40/LEC 315W Adapter Socket allows you to use reflectors with an E40 socket and install LEC/CMH 315W lamps without changing the entire equipment. Heat-resistant ceramic body, direct screw installation, and ideal compatibility for indoor cultivation.

With the E40/LEC 315W Adapter Socket it is possible to migrate traditional installations to ceramic technology without replacing reflectors. The design converts the standard E40 lamp holder into a suitable base for LEC 315 W bulbs, maintaining the geometry of the fixture and making use of the existing reflector.
The ceramic body dissipates heat and supports prolonged on/off cycles, helping to maintain the stability of the socket and the lamp.
The screw mounting is intuitive: screw into the E40 of the reflector, attach the LEC lamp and connect to the compatible ballast (CMH/LEC 315 W). This adaptation offers a cost-effective way to improve photon efficiency compared to classic HPS or metal halide, with less heat emitted to the canopy and greater spectral uniformity for both vegetative and flowering stages.
In tents and rooms, the adapter solves technology changes in minutes, avoids drilling or rewiring, and reduces waste by extending the life of existing hardware.
The ceramic format prevents deformation, maintains electrical insulation and reduces risks of arcing or carbonization. It is advisable to place a date label, check the socket tightness and keep the area dry and ventilated.
Together with LED grow lights for side support, a 315 W LEC lamp in an E40 reflector helps cover shadows, stabilize PPFD and improve flower density in cannabis plants.
In terms of operation, the adapter fits hybrid strategies (LEC + LED) or step-by-step migrations from HPS.
It is part of the essential electrical accessories for indoor to optimize budget in professional or home projects, and a perfect ally for those seeking efficiency without dismantling the entire lighting line.
For indoor growing the adapter allows the use of LEC 315 W lamps in already installed E40 reflectors. Less heat to the canopy, balanced spectrum and quick assembly promote compact growth and flowering with good calyx formation, maintaining the layout of the tent or room without renovations.
It is used to convert E40 to LEC 315 W base and thus install ceramic bulbs in E40 reflectors. Ideal for migrations from HPS; allows you to keep reflectors, save on hardware and improve light efficiency in cannabis cultivation with demanding cannabis plants.
Solution with excellent price-utility ratio: low investment that avoids buying new reflectors and accelerates the transition to LEC 315 W technology in setups seeking efficiency and thermal control.
