Hortilux Metal Ace Metal Halide (MH) Conversion Lamp, 1000W

Original price was: $128.99.Current price is: $114.99.

Most beginners don’t realize that:

  • HPS = red spectrum = flowering & fruiting
  • MH = blue spectrum = vegetative growth

Normally, you need two different ballasts to run both lamp types. The Metal Ace removes that barrier.

This lamp gives new growers:

  • Strong blue light for seedlings, clones, veg
  • Ability to switch back to HPS for bloom
  • A full-spectrum workflow without buying new hardware
  • A simple “plug‑in and grow” upgrade path

🔧 How It Works

  • It’s built as a metal halide lamp engineered to operate safely on HPS ballasts
  • No rewiring, no new fixture, no ballast swap
  • Just screw it in like a normal lamp
  • Provides MH spectrum for structure, internode spacing, and plant health

🌞 What You Can Grow With It

Vegetative crops & early-stage plants:

  • Leafy greens
  • Herbs
  • Microgreens
  • Seedlings & clones
  • Young cannabis plants (veg stage)
  • Ornamentals needing compact growth

It’s not a flowering lamp — growers switch back to HPS for bloom.

♻️ Lead-Free Construction

A simple but important retail point:

  • 100% lead-free
  • Safer manufacturing
  • Cleaner disposal
  • Better for greenhouse and indoor environments

“Metal Ace gives you metal halide vegetative spectrum on your existing HPS ballast — no upgrades, no rewiring, just better plant structure.”

Description

The Metal Ace is a metal halide (MH) conversion lamp designed to run on a high‑pressure sodium (HPS) ballast, or a dual-compatible 1000W digital ballast. That’s its entire magic:

It lets growers use MH spectrum on an HPS system (or dual-compatible digital ballast) without changing the ballast. Note, if you are using a dual-compatible digital ballast that has a manual selector for lamp type, choose the “HPS” setting when using these bulbs.

So a grower with a “one‑dimensional” HPS setup can instantly add the blue‑rich vegetative spectrum of MH — turning their lighting system into a full‑cycle MH/HPS grow solution.
