Sun White Spectrum

The spectrum that started it all and can grow almost anything is a full-spectrum light formulated to mimic natural sunlight conditions and is ideal for every stage of plant growth. High CRI 95 light accentuates plant coloration and makes visual inspection easier. Includes 660 nm (red) and 730 nm (far-red) wavelengths to boost photosynthesis rates via the Emerson Effect.

Love these lights

I love using these lights for my indoor garden. I love the amazing support of the company too. They go above and beyond to help their customers achieve success.

provided enough light to grow 2 trays per light. Am going to try 3 trays per light soon. A decent chunk of change, but very high quality.

Bought back my confidence in growing. Plants are taking off like weeds, was very deterred in growing until I bought these lights.

Great Product. Impressed with this product. My Bell peppers have done incredibly well under this light. Ordered a second light, have the 2 foot and 4 foot light. Seedlings grew so fast, needed the larger light to allow for them to spread out. The pepper plant leaves are broader than what I've grown under fluorescent T5. Another benefit, my plants are not leggy. Stalks are nice and thick. You can pull the light close to the plants after they sprout which was great at first. Eventually moved the light about 18? above them as they have grown larger and continue to grow. Plants have a nice Bush appearance. Also obtained great results with parsley and am now staring cabbage, tomatoes, basil and believe they will do just as well. This light definitely has given me a jump on the growing season which can be tempermental at times where I live.

These seedlings I started about 5 weeks ago are now thriving in my garden. I usually supplement those plants with others I pick up at the nursery to fill in gaps. Not this year. Retail inventory of seedlings was horrible, and so was the quality! And my latest happy discovery this seed-starting round is my new grow lamp system. I love trying different lighting systems in hopes of finally settling on a favorite. Over recent years as I was creating my Master Seed-starting online course, I trialed many options from basic fluorescent shop lights, to high-end LED rigs and more sophisticated T5 fluorescent systems. Recently I was invited to try and keep (at no cost to me) a 24W T5 lamp and fixture from Active Grow. I've trialed several more basic LED shop light rigs in the past but the results were just average. But not this one. It's definitely got my attention. These lamps were clearly designed for indoor growing, with high PPF efficiency (the amount of quality light frequency usable by the plants), and higher energy efficiency (none of the heat energy wasted by the fluorescent alternatives). Over 5 weeks of growing time under this system, the plants performed very well - no legginess, nice compact plants, great color, and no light-burn. You can buy just the lamps that plug and play into existing T5 fluorescent fixtures (4 lamps cost about $139), or you can buy the lamps and fixture for around $219 for the 2x4 ft size - perfect for evenly lighting 4 standard trays on a self. The seedlings here were growing under the Sun White Pro lamps and I was very happy with the results. I'm really looking forward to seeing how it performs for the next round of warm-season edibles starting in February. A link to this lamp system is in my instagram profile (@joegardener).

high performance, low cost. This lamp has been phenomenal since turning it on from day 1, I noticed immediate growth improvement. I could not be happier with the performance of these lamps and recommend to anyone.
