Telos Dynamic LED Grow Lights - UK-Built Full Spectrum LED Fixtures
Best for: Growers who want commercial-grade LED lighting, from a single efficient tent light up to a full 800W room fixture.
Our thoughts
Telos design and build these in South Yorkshire, and the batwing optics genuinely deliver a more even canopy than a lot of fixtures at this price point - no dark corners, no hotspot right under the light. The passive cooling means no fan noise and nothing to wear out either. If you want a fixture built to run for years rather than a season or two, this is where we'd point you.
The Telos Dynamic range is a family of full-spectrum LED grow lights covering four output levels, so you can match the fixture to the room rather than overpaying for headroom you don't need. All four run Telos's PWS1 Polar White Spectrum, tuned with 430nm violet-pump LEDs for a broad, usable spectrum across veg and flower, spread evenly by a patent-pending batwing optic lens rather than left as bare diode hotspots.
The range runs from the Dynamic 930 (320W, with a built-in Growcast control module) up to the Dynamic 2400 (800W). The 1200 (400W) puts out roughly 1200 umol/s of PPF at around 3.0 umol/J efficacy, delivering an average PPFD of about 1004 umol/m2/s over a 1m x 1m canopy at over 90% uniformity; the 2400 (800W) scales up to roughly 2400 umol/s PPF and an average PPFD of around 1364 umol/m2/s at a 65cm mounting height, also at over 90% uniformity. All models use passive cooling - no fans, no moving parts - and an IP66-rated waterproof and dustproof housing that's fully modular for servicing rather than sealed shut.
How it compares
Positioned as a UK-built alternative to the established commercial LED brands, at a more accessible price point.
- Versus Gavita's commercial LED range (e.g. the Pro 1700e), the Telos Dynamic line targets similar efficacy and even coverage via its batwing optics, at a lower cost of entry for growers scaling from tent to room.
- Versus Fohse's high-output commercial fixtures, the Dynamic range covers a wider span of output levels (320W to 800W) rather than committing to one large commercial format, better suited to growers scaling up gradually.
- Versus older single-bar or quantum-board style LEDs without optics, the batwing lens spreads light more evenly across the canopy, reducing the hotspot-under-the-light effect common with unshaped diode arrays.
You're paying commercial-fixture money, but you're getting UK design, real efficacy figures and a passively cooled build that should outlast a cheaper import.
Usage guidance
Choosing a model
Match wattage to floor area rather than tent height - the 930/320W suits a single small tent, while the 1960 (650W) and 2400 (800W) are built for larger tents or dedicated grow rooms.
Mounting height
Hang closer for higher-output models to hit peak PPFD uniformity - Telos quote around 65cm for the 2400 - and raise the fixture as plants grow to avoid light stress on the upper canopy.
Dimming and control
The 930 has a built-in Growcast control module; the 1200, 1960 and 2400 accept the separate Telos Manual Dimming Controller or Telos Lighting Controller for stepped or automated dimming.
Cooling
Because cooling is fully passive, give the fixture reasonable clearance from tent walls and ensure your tent has adequate air exchange - the light itself won't overheat, but a poorly ventilated tent still will.

Who this is for
- Growers moving from HPS or budget LED to a commercial-spec fixture
- Multi-tent or room growers who want one lighting family that scales from small to large
- Anyone who wants passive, silent cooling with no fans to fail over time
- Growers who plan to use the Telos Manual Dimming Controller or Lighting Controller for finer control
Best suited to growers ready to commit to a proper commercial-grade fixture rather than another budget upgrade.
Our take
The Dynamic range earns its price with real, quoted efficacy and uniformity figures rather than vague marketing claims, and the passive cooling and modular build point to a fixture designed to be repaired rather than replaced. Pick the wattage that matches your space rather than the biggest number on the page.
One we sell a lot of for growers who are serious about lighting. Proper kit, built to last well beyond a single grow cycle.
