Pure Light Energy Saving Lamp – Mixed Spectrum CFL for Grow & Bloom

The Pure Light Energy Saving Lamp is your best ally if you are looking for a versatile, cool, and easy-to-install lighting system that covers the entire life cycle of your plants. This CFL (Compact Fluorescent Lamp) offers a mixed spectrum, combining blue and red spectrums to support both vigorous growth and explosive flowering, all while keeping your electricity bill under control and temperature manageable.

Why choose a Mixed Spectrum CFL over traditional lighting?

Are you tired of fighting high temperatures in your grow tent every time you turn on the lights?

Traditional high-intensity bulbs (like HPS) generate a massive amount of heat, forcing you to invest in expensive extraction systems or air conditioning just to keep your plants from burning. Plus, having to switch bulbs between the vegetative and flowering phases adds an extra layer of hassle and expense that, quite frankly, you don't need.

The Pure Light CFL solves this by giving you a cool, all-in-one solution that just works.

With this lamp, you get a dual spectrum (2700K + 6400K), meaning it delivers the blue light needed for strong stems and the red light essential for fat buds. Because it emits very little heat, you can place it much closer to the canopy without stress, maximizing light absorption. It comes with an integrated ballast, so you can forget about heavy external transformers—just screw it into a reflector with an E40 socket, plug it in, and you are ready to grow.

Key Features and Benefits (FAB)

• Mixed Spectrum (Dual): Combines 6400K (Growth) and 2700K (Flowering). Advantage: You don't need to buy or change bulbs when switching the photoperiod. Benefit: Saves you money and simplifies your Indoor Grow management.
• Integrated Ballast: The electronic ballast is built into the base of the bulb. Advantage: No external equipment or complex wiring required. Benefit: A true Plug & Play experience that saves space and reduces setup time.
• Low Heat Emission: CFL technology runs much cooler than HPS or MH. Advantage: You can place the light 3-4 inches (8-10 cm) from the plants. Benefit: Prevents heat stress, preserves terpenes, and allows for growing in summer or tight spaces.
• High Energy Efficiency: Delivers a high lumen-to-watt ratio. Advantage: Consumes less power for the effective light delivered to the plant. Benefit: Lower electricity bills at the end of the month.
• Versatility: Available in 125W, 200W, and 250W. Advantage: Adaptable to different tent sizes. Benefit: Perfect for everything from maintaining mother plants to a full harvest in a micro-grow.

How to use the Pure Light CFL effectively

Using this lamp is incredibly straightforward, but a few pro tips will help you get the monster yields you are after. Since the bulb is heavy (due to the integrated ballast), ensure your reflector is sturdy. This light is a favorite for the Cloning stage and for keeping mother plants healthy because the gentle light doesn't stress young tissues.

For flowering, the key is proximity. Unlike HPS Grow lights, the light penetration of a CFL drops off quickly over distance. Keep the bulb horizontal and as close to the tips as possible (without touching them) to ensure the lower buds get enough energy to fatten up.

Frequently Asked Questions

Do I need an external ballast for this lamp?

No, the Pure Light CFL has an integrated ballast. You simply screw it into an E40 socket connected to the mains (220V) and it works immediately.

What is the best distance between the lamp and the plants?

You can get very close! We recommend keeping it between 5 to 10 cm from the tops of your plants. Check the temperature with your hand; if it doesn't burn you, it won't burn your plants.

Can I use this lamp for the entire crop?

Yes, absolutely. Being a mixed spectrum bulb, it is designed to support the plant from the first day of vegetation until the harvest.

Is it fragile?

Like all fluorescent tubes, they are delicate. Always handle the bulb by the plastic base, never touch the glass tubes directly with your hands to avoid grease spots that could create hot spots, and be careful not to hit it.

Personal Experience of Pevgrow’s CEO (Alan)

I've always had a soft spot for CFLs, especially for my "maintenance" tents. I use the 125W Pure Light specifically for my mother plants and rooting cuttings. It's just so much easier than dealing with excess heat in a small closet. The plants stay bushy with short internodes because I can keep the light right on top of them.

For beginners who are scared of the electricity bill or the heat management of an HPS, the 250W model is a fantastic entry point. You won't break records in yield compared to a 600W HPS, but the quality of the resin is top-notch because the terpenes don't degrade from heat. It's the stress-free way to grow.
