Join the sub-canopy lighting revolution! There’s no more cost-effective way for indoor farmers to improve crop quality and boost yields while lowering labor overheads.

Our incredibly efficient Arize® Life2 IP66-rated fixtures are the ideal sub-canopy lighting solution—with spectral options tailored for this precise application, we can deliver maximum efficiency and rewards.

Easy to integrate with your existing top lighting, Arize® Life2 fixtures can be installed in minutes to help boost flower production and quality beneath the canopy, meaning you can spend more time harvesting premium quality flowers and less time pruning and stripping.

Offered in two lengths, the new generation builds on its predecessor’s success with a 50% longer lifespan, doubled run lengths and efficacy levels peaking at 3.2 μmol/J.

*The Arize® Life2 is not compatible with the Arize® Lynk Gen 1 and Gen 1.5.

Choosing a Spectrum

Fixtures and spectrum recommended for common horticulture crops

Crop Stage Spectrum
Leafy greens Germination/ Propagation PPB or PKB as Blue promotes root creation. If you want to maximize your electrical efficacy (µmol/j), your choice is PPB. PKB will be more comfortable to the workers' eyes.
Leafy greens Reproductive PPR or PKR as red promotes biomass and flowering. If you want to maximize your electrical efficacy (µmol/j), your choice is PPB. PKB will be more comfortable to the workers' eyes.
Cannabis Propagation PPB or PKB because more Blue tends to keep the crop in a vegetative state and shorter in size. 
Cannabis Flowering PKR because cannabis secondary metabolite seems to be stimulated by the green portion of light while the low blue to red ratio seems to promote flowering in biomass development.
Ornamentals/ Flowers PPB or PKB will work well and allow growers to reduce plant growth regulators.
Microgreens Any spectrum will work, but high blue will keep the seedlings from stretching.  
Strawberry  PKR is very safe for all berry crops.  Intensity will be most important.
Vine crops/ Supplemental lighting PPR for supplemental lighting in the greenhouse. Academic studies (University of Arizona & Michigan) tend to agree that the best spectrum for greenhouse lighting is the most efficient one in efficacy thus higher micromols/joule should be considered. Tomatoes: PPR - Bell Peppers: PKB (Harrow research center) - Cucumber should be PKR.  If in doubt choose PKR.  It will work in every situation.
