LUMii SunBlaster 400W Dual Spectrum HPS Grow Lamp (E40)

LUMii SunBlaster 400W HPS Grow Lamp – One Lamp for Growth and Flowering

Traditional HPS lamps are a flowering specialist: plenty of warm red light for blooms and fruit, but short on the blue that keeps young plants compact and leafy. Growers have long dealt with it by swapping lamps halfway through. The LUMii SunBlaster removes that step. It's a dual-spectrum HPS lamp with increased output and extra emphasis on blue light, so one lamp supports both strong vegetative growth and heavy flowering.

Why It Lasts

• Crystal glass of constant thickness lets the light out evenly, with no bright or dim patches.
• No barium film: many HPS lamps use a coating that gradually darkens the glass and cuts output. LUMii left it out, so there are fewer gas impurities and the light stays cleaner and more stable over time.
• E40 mechanical double-layer fitting for a secure, durable connection.
• Rated lifespan of 32,000 hours.

⚠️ Please note: HPS lamps run very hot. Allow the lamp to cool fully before handling, and never touch the glass with bare fingers, as skin oils shorten lamp life.

🌿 Rose's Pro-Tip: HPS lamps fade gradually, long before they fail. Even a lamp that still lights up has lost a noticeable chunk of output after a year or so of daily use, so mark the date you fitted it on the cap.
