Description
The Maxibright PAR Meter is a very handy tool that helps growers measure the Photosynthetically Active Radiation (PAR) in their grow space – in simple terms, the amount of usable light your plants are actually receiving. By checking PAR levels, you can make sure your lighting setup is giving plants the right intensity for healthy growth, strong flowering, and bigger yields.
Compact and easy to use, the Maxibright PAR Meter takes quick, accurate readings, helping you adjust light height, positioning, or output to get the very best out of your LEDs, HPS, or CMH lighting system. For UK gardeners looking to fine-tune their grow room, it’s an essential piece of kit.

How to use
Hold the meter at the top of the plants, where the leaves are, and take readings across the canopy: under the centre of the light and out towards the edges. Then adjust the height, position or dimmer of the light and measure again.
- Seedlings and cuttings need much less light than plants in flower, so check again each time the plants move to a new stage.
- A reading that drops off sharply at the edges usually means the light is hung too close or is too small for the space.
For matching the light to the tent, see the LED wattage guide. More lighting controllers and accessories.
Questions
Why measure PAR instead of just using a lux meter?
PAR counts the light plants can use for photosynthesis. Lux is weighted to what the human eye sees, so it can mislead you, especially under LEDs.
Does it work with LED lights?
Yes. It works with LED, HPS, CMH and fluorescent grow lights.
Growers’ guides
- LED Grow Light Wattage by Tent Size (and LED vs HPS)How many watts of LED a tent needs: 300-500 W/m² in flower, a table by tent size, the Maxibright, Gorilla and LUMii fixtures that fit, and LED vs HPS.
- LED or HPS? Why the Best Growers Use BothTom's view from twenty years in the shop: run LED as the main light and add a dimmable HPS, metal halide or CMH for flowering weeks 3-7 for a better finish.
- Why Are My Plant Leaves Turning Yellow? Causes and FixesWhy plant leaves turn yellow or burn, from tomatoes to houseplants: watering, feed, pH, light, heat, pests or a deficiency, and what to check first.
