400W Grow Light Kits



Starting your first indoor grow can be a daunting task: too little light and your plants can freeze, too much light and your plants can fry. That’s why at GrowAce we offer 400w lights that beginners love and trust to give them a good first yield.

Each light kit comes with a Yield Lab 400W High Pressure Sodium Bulb that lasts at least 24,000 hours and contains 30% more blue spectrum than most HPS bulbs around, perfect for flowering or for your entire grow cycle. If you need a vegging light, just choose the HPS grow light kits with an MH bulb and you’ll receive the Yield Lab 400W Metal Halide Bulb that lasts up to 10,000 hours and is perfect for vegetative growth.

All 400w grow light kits also come with a Yield Lab 400W Digital Dimmable Ballast, which works with both HPS and MH bulbs, and can be dimmed from 100% of its power down to 50% of the light’s power. You won’t have to worry about overheating or short circuits, because these UL Safety Certified ballasts are protected against those and open circuits- part of the reason why they’re compatible with both 110v and 220v power outlets.

When it comes to reflectors, the sky’s the limit! All of the HID reflectors we offer are compatible with 400w grow light bulbs and ballasts, and we’ve made a kit for each and every one. If you need a wide spread of light across your grow, the Umbrella or Wing reflector will work best for your needs. If your plants need more intense light, or you don’t need too much spread for your light, Air Cool Hood and Cool Tube reflectors. Whichever you choose, all of the reflectors we offer have highly reflector surfaces and easy to install hanging ports.

But these grow light kits aren’t just for beginners. Professional, long time growers trust the 400W grow light to fill in dark spots of large grows, and low-scale growers love growing in closets or grow cabinets with them. Not to mention, these grow light kits come with a 1 Year warranty on their reflector and bulbs, and a 3 year warranty for all ballasts. So whether you’re just starting or starting your 5th grow, GrowAce’s 400w grow light kits will help give you the harvest you’ve been looking for.
