Turn any E27 socket into a growing space — 20W of full spectrum COB LED is enough to carry cuttings, seedlings and houseplants from veg through to bloom across a 30 x 30 cm footprint.

Designed in France by BloomLED, an indoor lighting specialist for over 10 years: the benchmark grow bulb, now in its V3 generation.

LED GROW LIGHT BULB

SpectraBULB X20 V3: the LED grow bulb that turns any E27 socket into a grow space

You do not need a full LED panel to get real results indoors. The SpectraBULB X20 V3 screws into a standard E27 socket and delivers a complete horticultural spectrum that carries plants from cutting to flower across 30 x 30 cm. BloomLED's benchmark grow bulb since 2009, now in its third generation.

20W SpectraBULB X20 V3 E27 LED grow light bulb by BloomLED for indoor growing

A full white spectrum, from veg to bloom

The full spectrum COB LED covers the entire photosynthetically active range (PAR), from the blue that keeps stems short and sturdy to the deep red that supports flowering. Unlike the old pink/purple bulbs, this horticultural white lets you read the true colour of your foliage and spot a deficiency straight away. One bulb covers the whole cycle: cuttings, vegetative growth and bloom.

Silent, compact and ready to run

The aluminium body handles cooling entirely passively: no fan, so no noise and no dust pulled into your grow space. At 125 mm x Ø 95 mm it fits a small tent, a grow cabinet, a converted cupboard or a plain desk lamp. Screw it in, switch it on: no external driver, no settings.

🌱 Full spectrum for veg and bloom

A full spectrum COB LED covering the whole PAR range: blue for compact plants, red to drive flowering, with no need to swap bulbs mid-cycle.

🔌 Installed in 10 seconds

Universal E27 base: desk lamp, hanging socket, BloomLED triple holder. No driver, no wiring, no electrical skills required.

🔇 Passive cooling, zero noise

The aluminium body dissipates heat without a fan. Ideal for growing in a flat, bedroom or office, where any hum would be noticed.

⚡ Just 20W for 30 x 30 cm

Minimal consumption for genuine horticultural results: cuttings, seedlings, herbs and houseplants short on natural light.

🕐 50,000 hours and 2-year warranty

A 50,000-hour lifespan, more than 10 years at 12 h a day, backed by a 2-year BloomLED warranty. Buy once, grow for years.

Since 2009 the SpectraBULB has been BloomLED's benchmark grow bulb. The V3 keeps that plug-and-grow simplicity while improving spectrum consistency: the ideal entry point into indoor growing.

How far from my plants should I hang the SpectraBULB X20 V3?

Allow 20 to 30 cm above the canopy during vegetative growth, and 15 to 25 cm in bloom to maximise PPFD. Check with your hand: if the heat feels uncomfortable at leaf level, raise the bulb a few centimetres.

How many plants can one bulb light?

It covers 30 x 30 cm effectively, which means one flowering plant or three to four cuttings. For a wider area, combine several bulbs on a triple E27 holder or step up to a more powerful model.

Can I use it in an ordinary desk lamp?

Yes, as long as the socket is E27 and the fitting is rated for 20W. It runs straight off 230 V mains with no driver. It is not dimmable, so use a timer to manage the photoperiod.

What photoperiod should I run?

18 hours of light to 6 hours of darkness works very well in vegetative growth. For flowering, switch to 12 / 12 with complete darkness. A simple mechanical or digital timer automates the cycle.

Why growers choose this timer

🌱 Stable photoperiod, consistent harvests

18/6 in veg, 12/12 in bloom: set the tappets once and the cycle repeats identically every single day. A steady photoperiod reduces light stress and the risk of plants reverting to vegetative growth.

⚡ 3680 W: from one panel to a full room

With 16 A of headroom, this timer drives a single horticultural LED panel just as happily as a power strip feeding several bars, an extraction fan or a nutrient pump. Just keep the combined draw under 3680 W.

🔧 Mechanical means unbreakable

No display, no backup cell, no menu to reprogram after a blackout — the dial simply resumes turning when mains power returns. That is the raw reliability growers want when a tent runs unattended for months.

BloomLED tip: keep the 'always-on' position for low-PPFD cloning stages, then switch back to timer mode as soon as plants enter vegetative growth. A photoperiod drift of more than 30 minutes is enough to unsettle sensitive flowering varieties.

Frequently asked questions

Is this timer suitable for an LED grow light with a driver?

Yes. LED drivers draw a brief inrush current at start-up that the 16 A contacts of this model absorb comfortably. For multi-driver builds exceeding 1500 W combined, BloomLED recommends adding a power contactor and using the timer purely as the pilot signal.

How do I set a 12/12 flowering photoperiod?

Push down the tappets covering your desired lights-on hours — for example 8 pm to 8 am — then rotate the dial until the arrow points at the real current time. Finally slide the side switch to the clock symbol. Each lowered tappet equals 15 minutes of light.
