I also have one is inside the tent sucking air outside. They are amazing lights by the way. **Q: Would one optic 8 light up my 4x4x8 grow tent?** A: I would think the Optic 8 should be enough for your size. I had the 6 in a 4x4 and it did great so i don’t see why the 8 wouldn’t work for you. **Q: How good is this light as far as getting big yields?** A: To be completely honest it’s the best light I’ve ever used next to 1000watt HPS... The only thing that I didn’t like is it makes the colas long instead of fat... You still get a great yield but it seems to make the plants taller then HPS... so if you have limited space... like if your growing in a short tent you might burn your tops a bit, but the light is awesome aside from that ## Customer Reviews ### ⭐ 1.0 out of 5 stars Poor customer service *by A***E on Reviewed in the United States on March 24, 2019* I will update this review over time currently it was shipped severally damaged Weston runs the entire thing with very little help it took me a week to get $150 by then the price dropped by $100 making it a little like a slap in the face. He can’t be reached called from morning to night Friday have emailed several times left messages to be called, no reply. It claims to have a lifetime warranty but if the company is non existent how good is the warranty. I am debating sending this back. But am scared to be honest they will simply keep the light and the money the service has been that bad. I want to love this light but the service is killing my soul. I will update as the weeks progress. Just if you get this brand expect very little from Optics. Please note several reviews have been bad from optics the last few months I have actually never wrote a review in my life. But this has been terrible. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Very good led Full Spec. Cob Light!! *by B***Y on Reviewed in the United States on August 30, 2018* I would of given it a five star if it had a dimmer like the 8 here does. By far a better light than a so called Gamma Blaster! Stay away from that one! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Stop wasting your money on any other lights *by L***S on Reviewed in the United States on April 2, 2019* This light is the real deal. I have a 4×4 tent and first started with a 1500 watt king led light it draws 260 watts which is not enough. You want at minimum draw of 300 watts from a light for 4×4 tent. The foot print of the king led was 2×2 area with absolutely no canopy penetration. I would average a yield from 6 to 10oz, so I decided I wanted to maximize my grow tent bit the bullet and spent the money and let me tell you it's worth every penny. First grow packed the tent over 2lbs. The light will really give you baseball bat colas all the way down. With this light you don't have to prune or defoiliate the bottom 1/3 or 2/3s of your plant. The light penetration is unreal. So do yourself a favor stopping wasting your time with cheap led lights and get the optic 8 + and maximize in your quality and return. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/66328467-optic-8-cob-led-grow-light-500w-uv-ir-3500k](https://www.desertcart.co.th/products/66328467-optic-8-cob-led-grow-light-500w-uv-ir-3500k) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-08*
