Dimming comes from being able to alter the driver output. So you can get Bridgelux strips and a dimmable Inventronics or Meanwell driver from digikey or a similar electronics supply. Just be sure to read the LED literature to make sure you get the proper driver type, like constant current, constant voltage, or combo constants. More on reddit.com

LED grow lights come on two flavors. Full spectrum white or red and blue. The red and blue correspond to the photosynthetic peaks. It's what your plant needs to live. The rest of the colors don't mean a whole lot. White full spectrum LED grow lights contain those red and blue peaks but they look white. Regular LED light bulbs only contain blue and yellow. When blue and yellow are mixed together it appears white. Yellow light also corresponds with the lumens, which is the measurement of how bright light is. Basically, yellow light is how bright our eyes think light is, but has nothing to do with plants. It makes sense that regular LED bulbs mix blue and yellow and mostly leave out red because why use it? plants need it but we don't. The next topic is power an efficiency. Plants need a lot of ppdf. To keep it simple PPFD is the amount of red and blue in the spectrum. Regular LED light bulbs won't have much PPFD. Grow lights are also typically 15 watts or higher with a very focused spectrum that has high amounts of PPFD. Your regular LED light bulb from Lowe's is probably only 3 watts, And the spectrum is mostly yellow So it has very little PPFD (only what is there from the blue). that means even if you find a regular LED light that's 15 watts it won't be nearly as efficient as a grow light that's 15 watts. Now if you have a houseplant, I would recommend a white grow light. You want something to match your decor. The trade-off with a white grow light is slightly less PPFD efficiency compared to a red and blue light. but you're talking only about a 10% difference if you're going with a high quality company. It could be a lot more with low quality brands. If you're growing plants in your basement or in a greenhouse, go with the red and blue based lighting. Those produce higher amounts of PPFD for the same amount of power consumption so they have much higher efficiencies. You wouldn't use regular white light for plants. Some old school greenhouses still use high pressure sodium or similar bulbs. These typically start at 300 watts. They aren't efficient by any means, but so much power is bound to grow anything. That high amount of power also penetrates leaves deep into the canopy for massive, crop producing plants. Hope that helps. A lot of bulbs have exaggerated numbers and are made really poorly. It's truly a market that's starting to be flooded with low quality Chinese products. Plant lights are on for 12 to 16 hours a day, and LEDs and the electrics have to stay cool or they fail quickly. Lastly, you should really find photos or a video of the product. A lot of bulbs that claim to be white are still extremely blue or pink And will look terrible in your home. Good luck!
