Miracle LEDCommercial Hydroponic Ultra Grow Lite - Replaces up to 150W - Daylight White Full Spectrum LED Indoor Plant Growing Light Bulb For DIY Horticulture & Indoor Gardening (604281) 4 Pack

I purchased a set of these grow bulbs at the end of 2019. I use them with a timer, for 12 hrs/day. Two of the four bulbs are still working well (~15 months); one bulb burnt out after ~1 year; one bulb started flickering after a few months and was no longer usable. I am happy with the lifespan of three of the four. I use them to supplement limited, indirect natural light, and my houseplants are doing well. Note that my houseplants do not require full sun. I just received a new box of four bulbs, and immediately noticed that the manufacturing has changed. The bulbs are slightly shorter and have a smaller diameter (see photo; new bulb is next to the box). The base is not glossy, like the original bulb. By eye, the new bulb seems as bright as its predecessor. Hopefully, its performance will be as least as good.

These bulbs appear to provide adequate illuminating for my house plants, but at circa $16 each they are very expensive, especially considering that of the four pack I bought in Dec 2019, one burned out after six months, while a second one died in August running 10 hours per day.A 50% failure rate in less than a year rates a poor review for product lifespan.Additionally, the equivalence rating compared to incandescent bulb wattage appears overstated per my calculation.

The lights started flickering after 6 months of use. There's options on Amazon that are much cheaper and do the same thing. Don't waste your money

All the flowers I had growing under these lamps died. I tried different flowers and plants incase it was a bad batch of seeds. I don't think I received 5 bad batches of seeds. These lights are really expensive. and to have everything die. well that sucks.

These are no different from standard 12W grow bulbs that are supposed to be "100 W" equivalent but they state 150W equivalent. The brightness is no different from a 5 dollar wal-mart LED bulb. They look exactly the same too right next to each other. Where do the 60 dollars come in for four bulbs? How does it have so many five star ratings?

I ordered a box of 4 and all but 1 was damaged. They seem to separate easily around the dome part of the bulb. I'm requesting a replacement to see if the next set is any better. But I think I've found another brand for my grow light needs - I'll be trying Sansi LED grow lights which come in 15w, 30w & 40w variations. Which might be better for larger house plants.

I got these in April and 2 of them already are not working 6 weeks about 6 hours a day and two are out.

These bulbs are not strong enough to keep plants alive in the house.
