LEC CMH bulbs are an essential element for indoor cannabis gardening for those growers using LEC CMH equipment. CMH LEC bulbs are the evolution of HPS and HM bulbs, their light emitting ceramic technology greatly improves the light spectrum and reduces heat emission.
CMH bulbs have a longer operating life than HPS bulbs. These long-lasting bulbs can complete up to 6 cultivation cycles, with no need to replace them as frequently as HPS bulbs. Ceramic discharge metal-halide bulbs produce between 100 and 120 lumens per used watt, which makes them highly efficient bulbs.
LEC CMH bulbs creates a full spectrum light, that closely mimics the spectrum of the sun, making plants feel more comfortable throughout their growing cycle. The bulbs emit a greater amount of μmol/m² and produce a broad spectrum light, from blue to red and far red. By using LEC/CMH bulbs it's possible to increase the yield using less watts and saving on your electricity bill, as plant production can exceed a 1w = 1.6g ratio.
It is advisable to replace the bulbs every 6 cultivation cycles to produce optimal results; otherwise the decrease in lumens and light intensity will cause a reduction in yields.
We stock the best spare bulbs for LEC/CMH lamps, across all supply voltage ranges, 315, 630 and 1000w, suitable for the LEC/CMH lighting kits available online at Alchimia.
