Photon 720W LED Grow Light

Photon 720W LED Grow Light - Full Spectrum Bar-Style LED Fixture

Best for: Growers running a 1.2m x 1.2m (4x4ft) tent or room who want strong LED output and daisy-chain control without paying premium-brand pricing.

The Photon 720W LED Grow Light is a full-spectrum, bar-style LED fixture built around a foldable, low-profile chassis with an integrated driver, designed to cover propagation, veg and bloom stages from a single light. It's rated at a PPF of 2304 µmol/s at 720W draw, giving an efficacy of 3.2 µmol/J - a genuinely competitive efficiency figure for a fixture in this price bracket. The unit measures 1043mm x 1083mm x 40mm, spreading light across a wide 120° beam angle via an optimised bar layout designed to avoid hotspots.

It offers 0-100% manual dimming, is controller-compatible, and includes daisy-chain ports for linking multiple fixtures under one control point in a multi-light room. The fixture carries an IP65 rating, meaning it's dust-tight and water-resistant, and the foldable frame with integrated driver keeps installation and handling simple rather than needing a separate remote driver box.

How it compares

The Photon 720W sits in the mid-tier of full-size LED fixtures aimed at 4x4ft-class grow spaces.

• Omega's Black 720W Plus LED, in the same wattage class, is rated higher on both PPF (2088 µmol/s at a similar draw with efficacy around 2.9 µmol/J for some variants) and comes with more configuration options, but typically sits at a higher price point.
• Maxibright's Daylight LED 660W Pro is a widely used mid-tier alternative at a slightly lower wattage, generally competitive on efficacy but at a smaller physical footprint.
• Lumatek's Zeus 600W sits at a premium price point with typically higher verified efficacy figures, aimed at growers prioritising top-tier performance over value.

The Photon's 3.2 µmol/J efficacy is a genuinely strong number for its price bracket, even if the very top-end fixtures from established brands can edge it out on raw output.

Usage guidance

Sized correctly for a 4x4ft (1.2m x 1.2m) tent or similarly proportioned space.

Hanging height
Start with the fixture roughly 45-60cm above the canopy for veg, lowering as plants mature into flower and adjusting based on leaf response and PPFD readings if you have a meter.

Dimming
Use the 0-100% dimming control to run lower intensity during propagation and early veg, ramping up through flower to make full use of the 2304 µmol/s peak output.

Multi-light rooms
Use the built-in daisy-chain ports to link several units to a single controller if you're running more than one fixture across a larger room.

Who this is for

• Growers with a 4x4ft (1.2m x 1.2m) tent or room looking for solid full-cycle LED coverage
• Anyone wanting daisy-chain control across multiple fixtures without paying premium-brand prices
• Growers who want a simple, foldable, plug-and-play install rather than a fixture with a separate driver box
• Budget-focused buyers who still want genuinely competitive efficacy figures

Best suited to standard 4x4ft-class tents rather than significantly larger commercial rooms.

Our take

This is a well-specced mid-tier LED fixture that covers a standard 4x4 space properly without asking premium-brand money for it. The efficacy figure holds up against the competition even if the very top-end fixtures can edge it out on raw output.

One we sell a lot of for new growers stepping up from HPS or a cheaper first-generation LED. Worth picking up if you want reliable construction that does the job.
