Boasting an incredible Photosynthetic Photon Flux (PPF) output of 950 µmol/s, this fixture produces super intense light at high efficacy (2.8µmol/J).

Energy Efficiency:

Powered by a Sosen LED Driver with a power factor exceeding 0.9, this state-of-the-art LED lighting fixture optimizes energy usage, reducing operational costs while maintaining peak performance.

Ideal Vegetative Spectrum

Equipped with a precise blend of Samsung LM281B+ Pro LEDs and Honglitronic SMD3535 660nm LEDs, the iLogic™ FS Plus 340W produces a perfectly tailored spectrum to drive strong, robust and vigorous growth.

Optional Upgrade: Iluminar Touch+ Grow Light Controller

The main difference between the Touch+ and the older Touch is greater dimming control. The old Touch controller could only control LEDs down to 50% dimming. The new Touch+ Controller can control dimming on LEDs all the way down to 20%

What makes the Iluminar iLogic Plus 340W different from other LED fixtures?

The iLogic Plus is Iluminar's flagship fixture line — highest efficacy, best build quality in their catalog. Its key advantage is zero downtime: both the LED bars and the driver are field-replaceable. If a bar fails, replacing it takes removing 2 screws and swapping the bar back in, rather than shipping the entire fixture out for repair for weeks.

What control protocol does the iLogic Plus use?

The iLogic Plus runs on RS485 rather than the standard 0-10V protocol most fixtures use. A 0-10V channel typically supports around 60 fixtures per channel; RS485 supports 200-2000 fixtures depending on adapter configuration, making it significantly more scalable for large commercial facilities. It's certified to work with Argus, Priva, and Growlink control systems.

Do I need a special controller to run the iLogic Plus?

No. Growlink and other certified RS485 systems will work with the fixture directly. An adapter is also available to step the connection down to a standard 0-10V/foam cord setup if needed, though this adds an additional connection point.

Is the iLogic Plus full-spectrum?

Yes, this is a full-spectrum configuration.

If a bar or driver fails, what should I do?

Don't disconnect the failed bar and wait for a replacement — leaving a bar connected (even if malfunctioning) maintains the correct wattage draw the ballast expects, preventing damage to the driver. Commercial orders ship with extra bars and drivers on hand specifically so facilities can swap immediately without downtime.

What is the warranty on this fixture?

5 years on the LED fixture, consistent with Iluminar's LED warranty across the line.

Im a home grower

These are the absolute BEST filters ive ever used. ive been buying them for the last 15 years now. Ill never buy another brand.
This is the ONLY brand ive ever found that I can run for 4 solid years without stinking up the hood. My wife hates that. let me say... that i swap them out before they fail and turn them into air scrubbers for drying flower. to be honest the ones ive swapped out after 4 years have NEVER failed. They still make work perfectly as air scrubbers. buying the other brands made me paranoid. the other brands fail before the first run is out! my wife doesnt like it when the neighbors are phoning about the odor.

Im a home grower with 45 years experience. yeah, really. I live in a nice neighborhood with lots of people walking their dogs by my house. I grow some fantastic living soil cannabis.
Many of the strains i choose absolutely reek.

I buy the 8x40 can lites.. they fit perfectly in the top of a 5x9 gorilla tent with cam/max fans. It doesnt get any better. I look for the stinkiest strains because they taste the best. Ive probably replaced them 3 times in the last 15 years? theyve never failed. You cant go wrong here. These are the ones youve always hoped for. ive had so many fail over the years i wouldnt have believed what im saying now. im going to buy some more next run.
Id give them 10 stars if i could.

The lights are high quality

The lights are high quality. The kit contains all the hardware needed to install the light in different ways. The controller (included) is nice, but a central controller is available that can integrate numerous lights.

Great sweetener for sweeter fruit & soil health.

Love the BioNova line and this sweetner is amazing. Super concentrated and great results. Used in high flowering & fruiting plats. Also works well on things like strawberries & peppers! I bought the 1L but either seems out of stock & hopefully HydroBuilder will still carry that size.

Best PK booster on the market

Best PK booster on the market: It has everything to make things go. it contains aminos, low ballast PK 13/14 boost - and at MOST you will use is 2ml/gallon. Best product on the market. Have used in many plants: peppers, strawberries & other HIGH fruiting/flowering plants. Amazing results. If in soil, use this with the soil supermix.

BioNova is the best

I love this product in my Hydroponics garden. This would also be a great primary A/B for your garden as well. SUPER concentrated, and the highest quality inputs i've used in the hydroponics space. 10/10
