LED Grow Light Library
Welcome to the ledgrowstore.co.uk LED Grow Light Library. This is where we take the lights we sell and go through them properly: real PPFD maps at every hanging height, coverage for veg and flower, power draw, efficiency, setup, and the questions our customers actually ask us. Every spec comes from the brand's own manuals and spec sheets, and we link to them so you can check.

How to read a deep dive
PPFD is the usable light landing on each square metre of your canopy every second, in µmol/m²/s. More is not always better. Seedlings need far less than flowering plants, and each deep dive gives the brand's recommended heights and dimmer settings for every stage.
PPF is the total usable light the fixture produces, in µmol/s. Efficiency (PPE) is how much of that you get for every watt, in µmol/J. Higher is better on both.
