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.
