How to Compare LED Grow Lights
When picking a light, focus on:
- PPF / efficiency (µmol/J) – more photons per watt = more growth per £ spent on electricity.
- Coverage / footprint – match light size to your grow space (e.g. 2×2ft, 3×3ft, 4×4ft tents).
- Spectrum – full spectrum (white + red + IR) supports all stages of growth.
- Features – dimming, daisy chaining, app control.
- Build quality – quality LEDs (Samsung, Osram) and drivers (MeanWell) last longer.
- Budget – expect £60–£450 depending on size and quality.
When comparing the top 10 LED grow lights UK, look beyond wattage — focus on PAR output, coverage, and real efficiency ratings.
