The SpectraBULB X20 LED technology was engineered to reproduce the wavelengths that plants actually use for photosynthesis. The full spectrum covers the blue that promotes compact growth and the red essential for generous flowering, delivering a rendering close to natural daylight. The result: sturdy plants, dense foliage and a controlled transition between phases, all with managed power consumption and very low heat output that protects your grow space.
Why choose this SpectraBULB X20 pack?
🌱 Full spectrum, growth & flowering
A single light for the entire cycle: the SpectraBULB X20 spectrum supports your plants from cuttings to harvest without changing lamps.
⚡ A genuine, efficient 60 W
Three 20 W bulbs offer an excellent light-to-consumption ratio, ideal for keeping your electricity bill in check while maintaining powerful lighting.
🔌 Plug & play, E27 base
Screws into a standard E27 socket. No external driver, no wiring: unbox, screw in, switch on.
🌿 50 x 50 cm coverage
The three light points distribute light evenly to avoid shadow zones and feed every plant.
🔇 Silent passive cooling
No fan: the LED bulbs dissipate heat passively for a quiet, discreet grow space, day and night.
🇫🇷 Designed in France by BloomLED
French design and the expertise of a growshop specialised for over 10 years, with after-sales support that truly understands indoor growing.
This pack suits both the beginner setting up their first small grow and the experienced grower looking for a reliable, modular supplementary solution. Because each bulb is independent, you can adjust the intensity by switching on one, two or three sources depending on the size of your plants and the growth phase.
Installation and usage tips
To get the most out of your SpectraBULB X20 pack, hang the holder using the one-metre cable roughly 25 to 40 cm above the canopy: move the bulbs closer during the growth phase for compact plants, then raise them slightly during flowering to cover more surface area. A simple timer (not included) lets you automate an 18-hour light cycle in growth and 12 hours in flowering, for a perfectly regular rhythm without daily intervention.
Remember to combine this lighting with good air circulation and suitable humidity: the SpectraBULB X20 LED bulbs run cool, but gentle ventilation strengthens stems and limits moisture-related risks. Occasionally wipe the surface of the bulbs with a dry cloth to maintain optimal light output throughout your grows. Delivered ready to use, this pack grows with you: add more SpectraBULB X20 bulbs as your growing space expands.
The simplest way to get started: open the box, screw in the three SpectraBULB X20 bulbs, hang the holder using the one-metre cable, and your 50 x 50 cm space is lit in full spectrum in under five minutes.
Frequently asked questions
What growing area does this pack light?
The pack of three SpectraBULB X20 bulbs effectively covers an area of about 50 x 50 cm, ideal for a small indoor grow, a compact tent or a few plants.

Absolutely. It is a plug & play solution designed to get started without technical knowledge: simply hang the holder and plug it in. No complicated settings.
Can I use it for growth and flowering?
Yes, the full SpectraBULB X20 spectrum is designed to support the entire cycle, from vegetative growth to flowering, without having to change bulbs.

SpectraBULB X20 V2 LED horticultural bul b is designed with E27 socket so that it can be used in many different fixtures. We have Plug & Play cables or clamps in our catalog. Feel free to check the accessories section

The SpectraBULB X20 is designed with CITIZEN's high performance COB LED. The full spectrum of 3500K is most suitable for plant development during growth. We use Citizen's 3500K COB LED because it offers a very high luminous flux for 20 Watts of consumption.

For growing plants, we recommend the use of this LED horticultural bulb. If you want to light your flowering plants, theSpectraBULB X30 bulb is recommended. However, if you are using another light source and want to increase your flowering output, this bulb can be used to supplement a sodium, ECO or other LED system of at least 30W.

The CITIZEN horticultural LED is cooled by means of a fine aluminum finned heat sink. This high-end device ensures a lifetime of 50,000H and makes the LED completely silent

This horticultural LED bulb has no wearing parts. You can use it for several years without seeing any difference in performance. It is guaranteed for 2 years. If you have any problem during this period, we will replace it with a new bulb.
