Lumatek HPS Mixed Lamp – Dual Spectrum Bulb for Growth & Flowering

The Lumatek HPS Mixed Lamp is the definitive lighting solution for indoor growers who demand professional performance, high lumen output, and the convenience of using a single bulb for the entire crop cycle. This high-pressure sodium bulb has been engineered to deliver a dual spectrum that perfectly mimics natural sunlight, ensuring your plants receive the precise light frequencies they need from the moment they sprout until harvest.

Is changing bulbs slowing you down?

Problem: Are you tired of the hassle and expense of buying separate metal halide bulbs for vegetation and HPS bulbs for flowering? Many growers struggle with the interruption of switching lights, risking damage to hot bulbs or, worse, forgetting to switch and stressing their plants with the wrong spectrum at the wrong time.

Agitation: Using the wrong light or low-quality bulbs doesn't just waste electricity; it directly impacts your yield. A spectrum that lacks blue light results in stretchy, weak stems, while poor red output leads to airy, small buds. Plus, cheap bulbs often lose intensity rapidly, meaning you are paying for light your plants aren't even getting, leading to the dreaded "why is my harvest so small?" moment.

Solution: The Lumatek HPS Mixed Lamp solves this by integrating a dual spectrum technology. It provides the intense red light (2100K) needed for massive flower production while enhancing the blue spectrum to keep plants compact and robust during vegetation. It is the reliable, all-in-one powerhouse that simplifies your grow while maximizing your results.

Why this Lumatek bulb is actually worth it for you

If you are looking for efficiency without cutting corners, this is your bulb. Lumatek has reinforced the internal components and the arc tube, making this lamp much more robust than standard HPS bulbs. This means it can handle the high-frequency output of digital ballasts without flickering or premature failure.

For the grower who wants to optimize their setup, this lamp offers an incredible balance of quality and price. You don't need to store extra bulbs or worry about compatibility. Whether you are running Grow lights with magnetic or electronic ballasts, this lamp delivers a high PAR (Photosynthetically Active Radiation) output that penetrates deep into the canopy, ensuring even the lower buds get enough energy to fatten up.

Most important features and benefits

• Dual Spectrum (Grow & Bloom): You get a balanced light output with enhanced blues for veg and intense reds for bloom, meaning you never have to switch bulbs mid-cycle.
• High Lumen Output: With 56,500 lm (400W) or 90,000 lm (600W), your plants receive intense light energy, resulting in faster photosynthesis and heavier yields.
• Long Lifespan (24,000 hours): You can run multiple crops with the same bulb, saving you money on replacements and maintenance.
• Reinforced Construction: Designed to withstand high temperatures and vibrations, giving you peace of mind that your grow room is safe.
• Universal E40 Socket: Fits almost all standard reflectors, making it an easy upgrade for your current setup.
• Optimized for Digital Ballasts: While it works with magnetic ones, it shines when paired with Lumatek digital ballasts, offering stable and flicker-free light.

Typical objections and clear answers

We know you might have some doubts before switching to a mixed spectrum bulb. Here is the reality:

• You think that mixed bulbs aren't as good as specific ones. In reality, Lumatek's technology has bridged the gap. Unless you are a commercial facility with separate veg and bloom rooms, the stress-free performance and results of this mixed bulb are superior to constantly handling and changing delicate lamps.
• You think that it might consume more electricity. In reality, a 400W or 600W bulb consumes the same power regardless of the spectrum. The difference is that Lumatek converts more of that electricity into usable plant light (PAR) rather than just heat.
• You worry about compatibility. In reality, if you have a standard E40 reflector and a matching wattage ballast, this bulb is plug-and-play.

How to use it safely and effectively

To get the monster yields this lamp is capable of, follow these simple steps for safety and performance:

1. Handle with Care: Never touch the glass with your bare hands. The oils from your skin can create hot spots and cause the bulb to burst. Use a clean cloth or gloves.
2. Secure Installation: Screw the lamp firmly into the E40 socket of your reflector. A loose connection can cause arcing and damage the socket.
3. Check Your Ballast: Ensure your ballast wattage matches the bulb (e.g., 400W bulb with 400W ballast).
4. Distance is Key: Keep the light at an appropriate distance from your Indoor Marijuana Seeds or plants (approx. 40-60cm depending on wattage) to avoid heat stress.
5. Cool Down: If the light turns off, let it cool down for 15 minutes before turning it back on to protect the internal gases.
6. Replacement: Although it lasts 24,000 hours, for maximum yield efficiency, we recommend changing bulbs every 3-4 crops as lumen output naturally degrades over time.

Frequently Asked Questions

Can I use this bulb for autoflowering plants?

Absolutely. Autoflowers love the mixed spectrum because they transition quickly from veg to bloom. This bulb covers their entire rapid life cycle perfectly.

Does this bulb work with dimmable ballasts?

Yes, Lumatek bulbs are designed to be robust enough for super-lumen switches or dimming, but always try to run them at their rated wattage for the best spectral stability.

Do I need a specific reflector?

No, any reflector with a standard E40 socket works. However, using high-quality Reflective material for grow room walls will help you maximize the light this powerful bulb emits.

Personal Experience of Pevgrow’s CEO (Alan)

I remember when I used to obsessively switch out Metal Halide bulbs for HPS the second I flipped the timer to 12/12. Honestly, it was a pain, and I broke more than one bulb in the process. When I started testing the Lumatek Mixed HPS, I was skeptical about the "blue" spectrum claim. But the results shut me up quickly.

The internodal spacing remained tight during the stretch, and the flower formation was just as explosive as with a pure HPS. For 95% of home growers, this bulb is the smartest choice. It simplifies your life, the reliability is top-tier (it's Lumatek, after all), and the plants look happy from day one to harvest. Just make sure you screw it in tight and keep your glass clean!
