Metal Halide Grow Light Bulb 250W – MH E40 Lamp for Leafy Growth | Lumatek

Lumatek 250W MH Lamp – Cool, Blue-Rich Light for Compact, Leafy Plants

Plants grown under a light that's too red tend to stretch, reaching up for light they can't quite find. Metal halide is the cure: a cool, white, blue-rich light (4,200K) that keeps plants short, stocky and leafy. The Lumatek 250W MH uses a quartz arc tube and a horticultural gas blend tuned for plant growth, with pulse-start technology for faster start-up, longer life and better output over time.

Perfect For

• Seedlings, herbs and salad leaves grown under lights
• Young plants you want compact rather than leggy
• Small tents and cabinets running a 250W ballast

Why It Works

• Blue-rich 4,200K spectrum for short, bushy growth
• Quartz arc tube with a horticultural gas blend
• Pulse-start for faster start-up and longer life
• 21,000 lumens and 323µmol/s PPF from 250W

🌿 Rose's Pro-Tip: many growers start plants under MH and switch to an HPS lamp when they start flowering. Both fit the same E40 holder, but check your ballast is rated to run MH as well as HPS.
