Esbaybulbs 40W LED Grow Light Bulbs E26 4 Pack, Full Spectrum Grow Lamp Red Plant Light for Hydroponics Greenhouse Indoor Plants

When they arrived, they all worked. This is good. I built a light fixture to house these bulbs for the floor of my grow tent. So I could have light shining on the bottom of my plants as well. Approximately 25% more yield.

First thing to know, these bulbs are not good for sprouts. The sprouts will climb too vigorously towards the lamp, and the sprouts will collapse from over-extension (this was only operating the lamps during normal daylight hours). I tried rotating the plants or adjusting their angles, and no. Do not use these for sprouts/starts.Second, these do work! My mature houseplants LOVE these lamps, including my cacti. Your plants will follow the direction of the light, though. This is not an 'area of effect' type of grow light. Best used for leafy plants, situate the lamp directly above the plant.I have a desk lamp shining on a vivarium in my house, and the plants inside all lean towards the lamp. I can't really reposition anything, so the plants look a bit.. uneven. They just grow towards the light.My cactus plants all lean over on their sides in order to maximize their light exposure/surface area. So these aren't great for succulents.Still, a very good price, these are very energy efficient. I have not had a single bulb burn out yet, it has been over 1 year of daily use. It is no replacement for good sunlight, but if you have limits like you cannot take your plants outside or near a window (as example, my vivarium would cook in a window and all the critters inside would hate me) and I can't put my vivarium outside for the day. So the plant light is great! My philodendrons love it too!My cacti (hedgehog types) have tan lines, and they totally just laid down to get the most surface area exposed to the light. They look funny now, but it adds character to my miniature indoor xeriscape.Summary: They work good! Best for leafy plants, don't use for starts, don't use for cacti. Mount directly overhead if possible, within 3-5 feet of target plant.

They worked great!

just what i needed

Work great and last a long time

Bought these to add to the light fixture in the room we use as a “ winter greenhouse” and they were an Amazon deal of the day. One of them died in a month and they aren’t as being as I was hoping but they work...or the plants don’t seem to mind lol. They are a small size and not expensive so I guess that should have maybe been a clue to not being bright, either way if you’re looking for a small plant light this could def he an option. Stars knocked off because of early death of one of them

I use these bulbs in conjunction with a lamp that is connected to a smart plug that is voice activated by "you know who." I turn the lamp on and off whenever I need supplementary light for some of my younger, less established houseplants and even those that require more light (i.e. succulents, tropicals). The bulbs are small and low profile, but have a wide spectrum of red, blue, and white LEDs that do not consume a lot of power. Despite that, they produce a lot of light for my needs, as my plants are only in a vegetative state and not flowering. Overall, I am very pleased with the purchase because they do not cost a lot themselves, won't increase my utility bill very much, and provide the light my plants need when natural light is unavailable. The bulbs are well made, packaged nicely, and simply work.

Good size , and good work
