LED lighting will help spare cash significantly due to the fact that they take much less energy to work. Likewise, LED’s radiate far less warmth contrasted to an HPS or CMH light, which additionally can bring down the cost of your energy bill for the entire area.

Yes, there will definitely be some changes and you will need to adjust your grow style to make sure you are optimizing your yields. For example, when switching to the Optilux, you can expect room and plant tissue temperatures to decrease. For this reason, you may need to make sure you adjust your temperature (HVAC) and watering schedule accordingly.
No matter what type of light you are using, you should always take precautions when switching between light intensities, spectrum, or entire fixtures. Typically with cannabis, when you move from the vegetative to the flowering stage, there is an increase of light and sometimes a change of spectrum. This can cause some strain on young plants. Our lights are no different and your plants should adjust within a few days.
The Optilux is our most popular horticultural light, and it has been used in several facilities, including Dutch Passion. We have a detailed specification sheet for the Optilux light.

The Optilux draws 633 W off the wall. To find the amperage, divide the wattage by the voltage. For example, if you are running 120 V, the amperage would be 5.28 A.
This really depends on the ambient temperatures and the movement of air in the room. This is a high-powered light designed for intense horticultural purposes, so of course, it will create heat! It is recommended to provide some air movement around the light. Do not place bare hands directly on the fixture during or immediately after prolonged use. Please use common-sense and be safe, as this is an industrial-grade piece of equipment. The Optilux creates about 1400 BTUs.
Yes! URSA Lighting’s Optilux is full-spectrum, and so it optimizes photosynthesis and plant growth during both the vegetative and flowering phases of cannabis growth.
Yield depends on many different factors, including genetics, other environmental conditions (temperature, fertilization, watering schedule), and the grower’s experience. It is easy to achieve 2 lbs per light using the Optilux.
Many growers who are pulling 3 lbs/light are doing so in 5’x5’ canopies (some even do 6’x6’). HPS has a very large reach and is able to support these bigger canopies. Naturally, the bigger the canopy, the bigger your yields will be. The Optilux performs best in a 4’x4’ canopy. In an area this size, we can achieve the same yields with 40% less energy!
No, the Optilux is 100% passively cooled. We choose to cool our lights via natural convection, as this is the most reliable method of heat management. We designed the Optilux for commercial grade use, making reliability a key aspect for us. Eliminating reliance on moving parts such as fans or liquid cooling gives much more peace-of-mind over the long run.
The Optilux, in fact, does have a spectrum with a very high amount of red light with a focus on the 630-660 nm range. However, we also put a lot of emphasis on the blue side of the spectrum, providing high amounts of 450 nm light to the plants. This gives our light the appearance of not having a lot of red, despite that not being the case. There is a common misconception that blue light (400-450 nm) should be reduced in the flowering stage. This misconception arose because HPS lamps used to be the old standard for flowering and predominantly emphasized the red side of the spectrum. Because of this, many LED manufacturers try to recreate the HPS spectrum (or even go for red/blue-only fixtures for marketing purposes). URSA Lighting has performed extensive research to disentangle the relationship between spectrum and plant growth. We have found that including high amounts of blue light is beneficial for increasing plant growth during the flowering stage. We have an entire article about the benefits of blue light for increasing cannabis yields.
Absolutely nothing. The Optilux is weather rated to IP65 standards. This means you could spray the Optilux down from any angle without worry. Humidity, mist, or even direct water application are no problem for the Optilux! Please keep in mind that the fixture is NOT submersible.
Those are spherical lenses designed to guide and direct light to the canopy. We use some of the most powerful COBs on the market, but all that power would go to waste if not properly controlled. By adding optical lenses to the fixture, we improve the intensity over distance and control the canopy coverage of our light.
Our recommended hang height is the optimal distance to achieve the maximum power over a 4’ x 4’, however this is not something that should be followed to a tee. Younger plants will need more than 2 ft of space to the light especially when initially flipping. We recommend starting out younger plants 4-5 ft away from the light and allowing the plants to grow towards the light. This works out nicely because you will not need to keep adjusting the light height. As the plant grows closer to the light, it will be mature enough to handle higher PPFD values. When are you growing you need to be attentive to the needs of your plants. This comes first – always. This same thing applies whether you are talking about lights, nutrients or other grow products. Whatever is written on the label is not necessarily what is best for the particular strain you are growing at a particular moment. Try it out, monitor the plant’s reaction and adjust accordingly.
