Exolux Pro Spica LED Grow Light - 100W

Out of stock
Only %1 left


Ideal for growing in spaces of 60cm x 60cm up to 90cm x 90cm, the Exolux Pro Spica is a 100W quantum board style LED unit, with high-quality full spectrum LED diodes mounted on a robust aluminium plate. This super cost-effective LED style allows for even distribution of light across your growing area, giving you all of the benefits of LED technology such as lower running costs and less radiant heat at an unbeatably low price.

  • High PAR efficiency of 2.7 μmol/W and total light output of 300 PPF
  • Superior Samsung 2835 & Epistar 3030 diodes
  • On board dimmer for precise control (20W, 40W, 60W, 80W, 100W options)
  • Ideal for propagation tents or for full seed to harvest growing
  • Full spectrum light output for vegetative and flowering cycles
  • Uniform coverage over an area of 60cm x 60cm up to 90cm x 90cm. We recommend 4 x units to cover a 1.2m square tent, although 2 x Exolux Pro Gemini or a more advanced Exolux Pro Sirius 630W would be a better choice at this size
  • Solid aluminium mounting board offers fantastic heat dissipation and robust feel
  • Mounted driver with manual dimming function
  • Includes hanging equipment - cables and rope ratchets
  • Passive cooling through aluminium board. No fans, no moving parts, less to fail.
  • 1 year manufacturer warranty

Even Spread – Total Coverage

This style of grow light has no lenses or reflectors, so they achieve coverage through evenly spaced diodes across an area. There’s no huge amounts of crossover light, and the usable coverage is not much larger than the unit size. For the Exolux Pro Spica, this area is 60cm x 60cm up to 90cm x 90cm but the spread and uniformity in that space is very consistent for even canopy growth.

Onboard Dimming

A key feature of the Exolux Pro Spica is the inclusion of an onboard dimmer. This lets you manage light intensity very accurately and makes the unit a great choice for a propagation tent or for a full grow through from seed to harvest, increasing the intensity as the plant grows. These lights serve particularly well as a vegetative growth light if you are running multiple grow chambers. Ideal for getting the plants well established before moving on to a more powerful lighting environment for flowering. That said, they are more than capable of getting a plant all the way through to harvest in smaller spaces.

Thermal Management

LED diodes produce heat when they are run and in the case of the Exolux Pro Spica, the robust aluminium panel conducts and dissipates this heat upwards into the top of your grow tent or grow room. As with all LED’s, there is reduced heat directed at your plant canopy but the heat does build and dissipate upwards from the unit for easy removal via your extraction system. The units do get hot to the touch, but this is completely normal – you can expect heat to be around 25-35% less than the equivalent wattage HPS units.

Why Are They So Cheap?!

The quantum board style of LED is a very cost-effective way of getting light to your plants. The LED diodes are mounted directly onto the aluminium panel and have no covers or lenses. This lack of advanced features makes their production costs much lower than some more advanced units. When you are talking about relative purchase price though, there’s no more cost-effective way of getting high quality LED light to your plants than an Exolux Pro Spica or the larger Exolux Pro Gemini. Both units are great entry LED’s to see the outstanding results that LED can achieve versus HPS or CDM fixtures – perfect for those in small spaces looking to grow 1-2 plants.

A great option with these lights is to use them in an Intermediate BudBox Pro White Grow Tent (75cm x 75cm x 160cm) growing one plant in a 56 Litre Rhizopot using a super soil such as Ecothrive Eco-Life Supercharged Soil. All you’ll need to do is add water and it’s a fantastic entry-level product combination.

Hanging Heights

  • Propagation: Hang at 60-75cm
  • Vegetative Growth: Hang at 45-60cm

How Do I Hang My Exolux Pro Spica?

Both the Exolux Pro Gemini and the smaller Exolux Pro Spica have convenient cutouts in each corner of the aluminium panel. They are easily hung using 2 sets of rope ratchets per unit (one ratchet per corner).
