CMH lamps (Ceramic Metal Halide) have high outputs in plant spectrum (PAR) but can be too high in UV when using their double ended lamps.

• The Borsilicate glass keeps light lumens and PAR spectrum high but helps reduce the UV to safer levels for your plants and yourself.
• It also helps protect against lamp failure and can be reused each time you replace the lamp, without having to replace the shield.
• All our CMH kits usually include one for safety for you and your crop.
• If you need a new one, then we can provide them here.
