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 ### ⭐⭐⭐⭐⭐ Review *by A***N on April 29, 2026* ### ⭐⭐⭐⭐⭐ Review *by J***M on September 10, 2023* ### ⭐⭐⭐⭐⭐ Review *by C***. on March 31, 2026* ## Frequently Bought Together - Spider Farmer 2024 New SF4000 LED Grow Light 4x4 with Samsung LM301H EVO High Efficiency & Dimmable Lighting, Full-Spectrum Commercial Plant Lights - AC Infinity CLOUDRAY S6, Grow Tent Clip Fan 6” with Redesigned Long-Life EC Motor, Custom 10 Dynamic Wind Speeds and 10-Level Oscillation, Weatherproof IP-54, for Hydroponics Circulation Cooling - AC Infinity Grow Tent Trellis Netting 4x4', Heavy-Duty Elastic Plant Net with Steel Hooks, Flexible Hydroponics Support for Grow Tents, Gardening, and Horticulture --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/147846284-spider-farmer-sf4000-450w-led-grow-light-for-indoor-plants](https://www.desertcart.vu/products/147846284-spider-farmer-sf4000-450w-led-grow-light-for-indoor-plants) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
