If you have decided on a quantum board light, there are only a few good options to consider. American brand (but Chinese made) HLG lights with their high prices, Mars Hydro TS or SP series lights with their lower quality Epistar chips, or these Spider Farmer lights.
With the increase in demand for white LEDs, more manufacturers have begun making them. They come in two forms: fixtures that use COB LEDs and fixtures that use a large number of smaller diodes. Whether you’re considering a Spider Farmer grow light or another brand, it’s important to consider a couple of things about grow lights that’ll help you make the best decision.

The white diodes give you light in every wavelength, with the 3000K diodes providing more reddish light and the 5000K providing more blueish.
Specifically, the premium brands like Fluence’s Spyder and the Gavita bar lights are far more expensive and not really any better. The results you get from both are basically the same. These grow lights are more energy efficient than traditional LED grow lights. That’s partially due to the fact they don’t use cooling fans. Another reason is the LEDs they used in these designs are newer versions of diodes compared to grow lights that were designed years earlier but are still for sale today. If you’re deciding between the SF quantum lights of the SE bar lights, there really isn’t much difference. Having separate bars allows air to flow through the fixture, which helps cool it. The bar design spreads the light more evenly across the canopy compared to the flat board design seen on grow lights like the SF series. The bar design also allows heat to dissipate off the grow light better, as there’s more room for airflow around the LEDs. Seedling stage: 400μmol/m²/s, with a LED grow light distance between 24-36 inches above the plant canopyThis 5’X5′ grow tent is spacious enough to accommodate 9-12 full-size plants throughout their entire growth cycle, from seedling to harvest The one downside to getting a bar-style grow light is the bars may prevent you from reaching the ceiling of your grow tent as easy, compared to a flat board grow light. It’s a small inconvenience but I think the benefits of the bar style grow lights outweigh this negative. The dimmer and 6 foot extended driver cord allows you to detach the driver and hang it outside your grow tent to reduce heat. Both of these features come standard on the SE series models. Generally speaking, the minimum PPFD worth required for plant growth is 400μmol/m²/s, and the optimum PPFD value that can be absorbed by plants is 1200μmol/m²/s. Anything beyond that will possibly hurt your plants.
This 5/5 star review said, “ I love the sf4000 because it has high output with little draw at only 450 W. It outperforms my 600w HPS and runs cooler and uses less electricity. My yields are great with high-quality medicine and I couldn’t be happier.” Full Spectrum & Dimmable: Full spectrum (3200-4200K,4800-5000k, 650-665nm) is perfect for seedling to harvest, to adapt to each phase of the plant cycle. The dimmer knob is an ideal for growers to adjust the light intensity according to different growing stages. Most HLG lights have white light with added 660 nm deep red or blue, depending on the fixture. The Electric Sky lights feature white light with deep red and IR. The Mars SP and TS lights vary. Some have deep red in addition to white, while others have the same plus IR and UV.

In addition to that, with Chinese companies you always have to deal with dishonesty, especially when it comes to the wattage. In this case, the SF 1000 does not use 1000 watts (it uses 100w) and it is also not equivalent to a 1000w HID light (about 200w). The 2000 and 4000 are also off by a factor of 10. The SE7000 is strong enough to get near maximum yield from your cannabis plants. When measured in a 5×5 foot grow tent, the SE-7000 emits between 900 and 1100 PPFD from 12 inches above the canopy. If you’re considering one of these grow lights you may be considering the other style of grow light from Spider Farmer as well – the SE Series grow light, which is a bar style grow light. Fully dimmable and daisy chain ready, the Spider Farmer SE5000 LED Grow Light offers precise control over light output. With easy fingertip adjustment from 10% to 100% power, the Spider Farme SE5000 LED Grow Light is suitable for all stages of growth, from delicate seedlings to resin-rich flowers. The improved dimmer box allows power-savvy cultivators to adjust electricity usage, optimizing efficiency and minimizing wastage. For some customers, this product seemed like the perfect light for their situation. “ Plants loved it right away! I tried a lot of lights for the past 5 years, this one is a beast! No hot spots, even coverage and of course, those diodes for that price, you just [can’t] go wrong with that light”
