Impressive Lighting Solution for My Indoor Grow Tent! Review: I recently purchased the Spider Farmer SF 1000 LED grow lights, and I must say, I'm thoroughly impressed! I initially bought one unit to grow a single plant. but I was so satisfied with its performance that I ended up purchasing three more over the span of a week to fill out my 4x4 grow tent.

They truly value their customers and go the extra mile to ensure satisfaction. In terms of product quality, the SF 1000 is top-notch.

These LED grow lights consume minimal power while delivering impressive light intensity. They're environmentally friendly and help keep electricity costs in check, which is a big plus for any indoor gardener. The installation process was hassle-free, thanks to the well-designed hanging kit provided with the lights. It made mounting them in my grow tent a breeze.

It has exceeded my expectations, and I'm sure it will do the same for you. Happy growing! Review: Great Light for about 1 year: UPDATE 10/15/21 - I have purchased 2 of these SF2K's . I bought the second light not long after the first, because INITIALLY these lights hold their own so to speak. The only issue, and hence why the 3 stars is, after about 1 year, the dimmer switch goes out. The light will flicker if it is used. Both of my lights still work on full power, but now I have no way to dim them and will have to purchase another light for my lower power needs. Very disappointing, but thankfully the second light's switch went out RIGHT, before I purchased a 3rd. UPDATE 10/8: A few days after leaving a review of the 2 SF2K's I purchased, Spider Farmer customer service reaches out to me. They were extremely courteous and helpful. After sending them a video of my issues, they offered to either fix them or send the appropriate parts for me to repair it myself. After watching the 2 repair videos they sent, I decided to accept the repair parts, as the repair looks really basic and simple. No special tools required or anything to that effect. That said, I've added a star to my previous rating. If these new parts last, I will surely raise my rating to 5 stars, as these lights are amazing when functioning properly. The brightness and spectrum are amazing and well worth the price imo. They produce very little heat, and the energy they consume are almost undetectable. Most importantly, I feel confident in their customer service at this point and will most likely purchase their SF4K. Update 10/15: Because of Spider Farmers most excellent customer service, not only have I added the 5th star, but I will most certainly be buying myself the SF4000 for Christmas. It's nice knowing your money is well spent. I think all initial purchases are a gamble, but Spider Farmer, I can honestly say, is a safe bet! Not to mention, these lights are POWERFUL. To the extent, you have to be sure not to blast your plants with TOO much lights. Use as directed and adjust accordingly. ## Features - Cutting-Edge Upgraded LED Chips for Unrivaled Performance: All-new premium upgraded LEDs with 2.7 µmol/J system PPE and increased diode count, delivering nearly identical performance to our previous version.

The normal delivery time has resumed now. Don't worry.If you have any questions, please contact our customer service directly **Q: 220 conversion ? Cut the plug off ? Really ? I have a 220 line and the plug doesn’t fit !** A: SF4000 can work in 100V-277V, no need to replace the plug and power cord, only need to buy a plug adapter, you can easily convert to 240V **Q: Can u run these on 240?** A: Yes you can I’ve just bought and used these adapters with the spiders. I found them on eBay: 3pc 3-Prong 110-120V to 220-240V Plug Adapter 4 Ballast Grow Light Fixture Power. They are rated for 110 up to 270v. I use a powerbox so I ended up with too many timers and found the perfect adapter **Q: Can two of these lights fit in a 5x5 tent ?** A: maybe, but I doubt it. This light is overkill for 3x3, perfect for 4x4, and barely adequate for a 5x5 by itself. If you have the money to get two of these, you can get the Spider Farmer bar lights that would be perfect for a 5x5 and cost you way less than 2 of the sf4000 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive Lighting Solution for My Indoor Grow Tent! *by J***M on September 10, 2023* Amazon Review for SF 1000.
