The 4XL and 8XL
Purchased together and both are
Very well built and light output is amazing
Just put out my first harvest and very happy with the results
The optic 4 XL has lived up to all the hype. In a 4x4 space at 18in above the canopy it really causes the flowers to swell nicely. Minimal heat produced with blinding light. The dimmable feature is convenient for watering and pruning without interrupting light exposure to the plants. Quality is superb. I would highly recommend this light.
This light is top quality in build and in results. Had issue with my humidifier first day growing with new light. Humidifier never turned off and ran constantly. I didn't have my carbon air filter running as i just transplanted clones. Humidity was well above 100%. When I opened my tent door a billow of humidity came out and everything in my tent was dripping with water. The Optic 4 xl had water dripping through the fans and pooled in the cob lenses. I removed the lenses and never turned off my light cause I had plants growing and my light is still working perfectly every fan every diode the knobs absolutely everything works perfectly on it even though it was like someone poured a gal of water on top of the light and it didn't even phase it... haven't flowered with it yet but man is this light killing it in a 4x4 tent while vegging! Happy growing
The light seems very bright and I love the adjustability of veg and bloom switches. The light adds almost nothing in the way of heat to my grow. I would have given 5 stars but have yet to finish a grow yet.
Purchased the optic 4 xl a couple months ago. It has been awesome in flower! Biggest nugs so far. This is my 3rd optic light. Dosen't get any better for the price. Use to get free west coast seeds but haven't received them with my last order but other than that these lights are amazing
