What improves when you switch

1. Better spectrum = healthier plants

CMH bulbs produce a wide, natural spectrum with strong blue, red, and UV. This means:

  • Stronger vegetative growth
  • Tighter internodes
  • Better colour and morphology
  • Improved flowering quality

The 3100K and 4200K options make it easy:

  • 4200K → vegetative growth (more blue)
  • 3100K → flowering (more red)
  • Or use either one from start to finish.

2. Less heat = easier environment control

A 630W CMH runs much cooler than a 1000W HID. This gives new growers:

  • Less risk of heat stress
  • Easier temperature control
  • Ability to hang the fixture closer to the canopy
  • Better light penetration without burning tops

3. Lower power use = lower hydro bills

Switching from 1000W to 630W reduces energy use by up to 70% when you include:

  • Lower wattage
  • Lower cooling demand
  • Longer bulb life

This is one of the easiest selling points for new growers.

4. Better bulb life and stability

CMH bulbs:

  • Maintain spectrum longer
  • Lose fewer lumens over time
  • Have a high CRI (90) for natural plant inspection
  • Are double‑jacketed and safe for open fixtures

New growers appreciate “less replacing, more growing.”

Description

A 630W CMH gives you the full spectrum your plants want, with less heat and lower hydro bills. It replaces a 1000W HPS or MH with better growth, better colour, and better yields
Switching from a 1000 watt high pressure sodium or metal halide system to a Lightspeed 630W ceramic metal halide system will increase the growth, health, and yield of your plants and will lower your energy costs by up to 70%. The wide spectrum of our Lightspeed CMH bulbs allows either the 3100k or 4200k to be used from the vegetative phase straight through to flowering, or for maximum growth and yield begin with the 4200k bulb for vegetative and then switch to 3100k for the flowering phase.

The lower wattage of our 630W CMH bulb versus the standard 1000W HID bulb translates to less heat being expelled from the bulb and the ability to place the grow fixture closer to the canopy, increasing light intensity and canopy penetration. This double glass jacketed lamp features a double ended lamp base and is rated for open fixture use. The ultra-efficient ceramic metal halide system can do the same job as MH and HPS with better results, using less power and emitting less heat. Lightspeed 630W ceramic metal halide bulbs pair well with any double ended 630W system, like our Lightspeed CMH DE 630W System or the Lightspeed Digital CMH 630W Ballast.

Specifications:

  • Ultra-efficient double ended bulb

  • Reduced branch spacing and tight internodes
  • Watts: 630
  • Kelvin: 4200
  • Color Rendering Index (CRI): 90
  • Initial Lumens: 67000
  • Base: Double Ended Open Pin
  • Length: 394mm (15.5”)
  • Diameter: 55mm (2.17”)
