Iluminar 315 Watt SE CMH Bulb Spec SheetThe ILUMINAR CMH Single Ended Lamp is a natural white grow light with a proprietary phosphor coating on the outside of the arc tube to provide a rich spectrum and superior color quality.
The 315W single-ended bulb is a medium wattage light with an enhanced spectral output that gives off a crisp white light for indoor gardens. It’s designed for maximum efficiency and is available in 3K, 3K+Red, 4K, and 10K color temperatures.
Many growers prefer CMH lighting because of the power per watt it can deliver as well as the remarkable PAR spectrum that most closely matches the deeply penetrative power of the sun. Save money on your garden with the SE 315W by not only using less power but also running cooler than the HPS and MH alternatives.
The ILUMINAR single-ended 315W CMH lamps are perfect for propagation, vegetative as well as flower stages. The 3K+Red 315W is designed to enhance resin production in plants by giving a taller peak in the far-red to stimulate metabolic activity during flowering.

What is this Iluminar 315W CMH bulb rated at 4,200K?
This is a 315W CMH replacement bulb at 4,200K color temperature, designed for use with compatible Iluminar CMH fixtures.
What is the warranty on this bulb?

Should I be aware of true wattage draw vs. the labeled wattage?
Yes — actual wattage draw on HID ballasts often runs higher than the labeled rating. For example, a fixture labeled 1000W may pull 1085W or more depending on the ballast's boost setting, and some configurations reach up to 1150W. Since wattage translates directly to heat output, this matters for accurate BTU and HVAC load calculations.
