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

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.

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.

EACH light consumes 6 watts of power so the description is a little deceiving. At first glance you might think each lamp is 24 watts or consumes 24 watts. All are functioning fine and are positioned close to the vegetation without burning the leaves. Our two plants (about 14" tall) are happy and growing well. I should note we are using four compact fluorescents as well each rated at 12 watts. So a total of FOUR 28PCS Full Spectrum High-efficiency Epistar® 5730SMD LED bulbs and FOUR 12 watt compact flourescent bulbs (regular house hold CFL's) These full spectrum led bulbs are fine for a small growing space ....maybe for a few plants. IF you are thinking of lighting a bigger growing space you would want to consider purchasing bulbs with much higher ratings.

Great little grow lights! Your best bet for growing a good size plant with these little things is to get a 4 bulb socket and hang all 4 of them above about a 10" diameter pot full of soil with your seeds in them and turning them on and off as necessary possibly with a timer and you'll grow a great plant. Or for small Plants just use them one at a time in a regular desk lamp. Whats great about the multi-pack is is that it gives you the option (possibly with a couple of extra items, such as extra lamps, or multiple bulbs in a lamp or hanging lamp with extra bulb sockets or splitters) of using them many ways@! The skys the limit when you've got 4 of these little things to play around with.

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.

These seem like a good lights, i got them late in the growing season so i csnt really comment in their use. It kept the plants i had alive, but they didnt get very big and a few did die until they went outside. I'll try agim this winter and update the results.

Winters in the upper midwest can be tough on plants both indoor and outdoor. We bring some of them in for the winter and then we have too many plants for the amount of windows we have that have any amount of sun shining through them. These bulbs are inexpensive but seem to work really well for our indooor plants. I put them in a clamp light and turn them on for 6-8 hours a day and all the plants respond really well. Maybe it's the IR and UV in addition to the red and blue LEDs. I don't know. Just trying to keep them alive so we can get more plants and expand the problem.

I have set up a couple of cupboards to grow some seedlings until the weather gets warmer and they can make it outdoors. The tiny sprouts are growing into healthy seedlings under these little lights. I place one light over each plant, about 2 inches away. The plants are looking healthier and show better color than the plants I have under compact fluorescent lights. Also, these little lights generate almost no heat. I also bought a much bigger 100 watt version of this light ($26) , but I can't it works any better, just costs more.

I use these in winter on a few of my indoor plants and some seedlings. They are great I have them connected to smart plugs to give 8 hours of proper light per day. My plants are happy! These are no nonesense as they plug into regular lamp fittings.

El envío po Amazon sin duda es de lo mejor. Sin embargo uno de los 4 focos del envío salió fundido porque no prende. Ahora voy a tratar de contactar con el vendedor para preguntar que procede... Les actualizaré el reporte.

Recibí el producto un día antes del estimado, es muy buen servicio de distribución, lamentablemente un foco venía con defecto, una hilera de LED ni encendía ,el de la izquierda de la foto, color amarillo ja luz, devolví producto , rápida devolución del importe y he solicitado de nuevo el producto al mismo proveedor, misma marca, buena experiencia, excelente servicio de ambos.

Works great. Maybe a little flimsy, time will tell.

These work very well. After the first night of 2 in my table lamp, and 2 in my overhead light fixture, all my little seedlings were pointed towards them. After 4 nights I have noticed a significant increase in their growth. You can't beat the price for these grow lights either! They arrived a day early which was a bonus.
