Pure Light CFL E40 Bulb – Low Consumption from 125W to 250W in Bloom and Mixed GreenPower

Low-consumption CFL bulbs from Pure Light with an E40 socket. Their big advantage: they do not need a ballast. They screw directly into an E40 lamp holder and work, making them the simplest and cheapest option to get started, for mother plants or small grow cabinets.

Two spectrums

• Bloom 2700 K: warm spectrum, oriented toward flowering.
• GreenPower 2700 K + 6400 K: mixed spectrum, combines warm and cool in the same bulb, so it works for growth and flowering without changing lamps.

Which power to choose

CFLs generate little heat, so they can be placed very close to the plant. As a reference: 125 W for cuttings, mother plants and 40-60 cm cabinets; 200-250 W for small full-cycle grow cabinets. For large areas, an LED or an HPS performs better per watt.

🔴 The supplier does not publish PPF, µmol/J or lumens for any of these bulbs. We do not invent figures. Note: the original sheet described the 200 and 250 W models as “Grow,” but they are Bloom 2700 K; this has been corrected. The weights are estimates.

At GrowIndustry we only work with products of proven quality and trusted brands.

Each item goes through a check before shipping to ensure you receive it in perfect conditions and ready to use.

Your satisfaction is our priority.

1. Elige GreenPower si quieres una sola bombilla para todo el ciclo.
2. Elige Bloom 2700K si solo la vas a usar en floración.
3. Rosca la bombilla en un portalámparas E40: no hace falta balastro.
4. Colócala en vertical para que disipe bien el calor.
5. Acércala a 15-25 cm de la planta y comprueba con la mano.
6. Sustitúyela cada 8-12 meses de uso: la CFL pierde salida gradualmente.
