GE Grow LED Light Bulb, PAR38 Flood Light, Indoor LED Grow Lights for Plants, Seeds and Greens, Balanced Light Spectrum, 25,000 Hours Lifespan, 50 PPF, 1 Pack (Packaging May Vary)

Seeing as how popular indoor container gardening has become - and, accordingly, how lucrative it now is to sell indoor grow lights - it is a bit difficult to find a light that you feel at all confident will actually be effective for your indoor plants. I’ve scrolled through what seems like countless products that purport to emit awesome spectrums that are totally sweet for plant growth (and, oddly, seem to feature the exact same “wavelength graphs”), or that tout their (sometimes slightly deceptively calculated) wattage - despite the fact that a fixture’s wattage tells you near to nothing about how useful a light will be in aiding a plant’s growth (wattage is, put simply, a measure of the amount of electricity used to run an electrical device, not a measure of that device’s energy output). It’s been a confusing and sometimes demoralizing search (well, as demoralizing as online shopping can honestly be), and I’ve felt very much in over my head I’m trying to choose a product that won’t be a waste of money or harmful to my plant friends.I am reviewing this particular product very positively, not simply because it works and is bright and has seemed to be very helpful in my attempt to keep a fussy dwarf orange tree alive over the dark cold winter, but also because I appreciate having been given the kind of information a consumer actually needs when trying to find a good, effective grow light.You’ll see the term “PAR” right in the title of this product, front and center; PAR, or Photosynthetic Active Radiation is essentially a measurement of light emission within the photosynthetic range of 400-700nm, which is the area of light that plants use for photosynthesis, or to grow. This is a really valuable specification to have in selecting an effective grow light, and I can’t imagine why so many of the other (often even more expensive) grow light fixtures for sale here don’t include this information in their listings.Hopefully, I haven’t come off as overly pedantic, I don’t mean to lecture anyone on the science of plant grow lights (admittedly, I know very little myself!), but I do remember my first searches for a good, solid grow light fixture and how frustrating it could be to feel that I wasn't getting any really useful information from so many of the products I found. I spent quite a bit of money on fancier-looking, often more expensive but ultimately less useful lights before I found this one, and I hope that this information is helpful to you, prospective buyer! I wholeheartedly recommend this bulb to anyone who needs some bright, direct auxiliary light for their indoor plants. One last point: this bulb is quite heavy (not really suitable for gooseneck/clip on task lamps), so keep that in mind while making your decision.

Hey there, just wanted to share my excitement about this awesome product I've been using for about a month now – it's seriously amazing! My plants are loving life and thriving big time. I mean, within just a week, I noticed new growth popping up all over the place. Even my indoor orange tree, which was craving some good light, started sprouting new leaves after just a couple of weeks with this bulb.Sure, the bulb itself is a bit on the heavy and bulky side, but pair it with a cool light fixture, and it works like magic. The light it gives off is bright and white – perfect for my little green buddies. Mine's tucked away in a corner, yet it throws enough light to keep all my plants happy. I've tested out different brands and lights before, but none have given my plants the same boost as this one. You bet I'm gonna grab another one when the time comes! 🌱✨

I decided to go with this grow bulb because it was the only one I could find that listed it's ppf value in the specs. I had also been previously using the GE BR30 LED grow light (16 micro miles/second) for about 7 months prior to receiving this one and I felt like my plants were doing really well, but I wanted to see if they could do better, grow faster, and produce larger leaves. I don't yet know if 50 micromoles is ideal for my indoor plants and environment (I have them on a shelf next to my western facing window in southern California where it's always sunny), but I will give an update when I see the results. The bulb is heavy, weighing in at 1.2 lbs on my scale. However, fortunately, my lamp can handle the weight. I'm using the Ranarp Ikea work lamp. I have it positioned to give as many plants a boost as possible while prioritizing my FLF, but I could position it to prioritize the top shelf no problem. I've taken a few photos with the footcandle readings at different positions of my setup so you can get a visual of the amount of light you'll get at different distances. My FLF is 26" away and gets ~758 fc. Bottom shelf 44" away gets ~558 fc, second shelf 32" away with the light directed at it ~997 fc, third shelf 24" away gets ~222 and top shelf 22" away gets basically nothing from the light. Hopefully that makes sense... The bulb gets pretty hot but I can keep my hand on it for about 15 seconds, not comfortably though. It's bright, but not harsh and a little on the warm side, much like the BR30 but a bit brighter. Gives my plants the beautiful spotlight they deserve. 👌
