Review: Totally Worth It! - Well worth the money. Plants that did not winter well last year when I used lights that are obviously targeting frugal shoppers. I spent the money this year, and what a difference. I actually had to reduce the light intensity because I don’t have room indoors for the plants to grow as much as they would if I left light at full intensity. Setup and assembly were easy. Controls are high quality and easy to operate and understand. Light level, outstanding.

## Questions & Answers

**Q: Why it s my delivery time almost a month after purchasing?**
A: Due to the COVID-19, our products are in transit for a long time. 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

### ⭐⭐⭐⭐⭐ Perfect for starting a family...
*by D***B on November 14, 2025*

I absolutely love this grow light. It has top of the line diodes, great heat dissipation, and couldn't be more perfect from seedling growth (the dimmer is quite valuable) through early and mid vegetative stages. If only growing one plant it may be quite capable for flowering stages as well although I start using a bigger light in this stage of growth. The price tag is very agreeable as well considering the array of much more expensive grow lights on the market. Your girls will reward you for your months long efforts.
