SANSI 600W LED Grow Lights, 4-Head Full Spectrum LED Plant Lamp with Clip, 4000K Sunlike, Timer 4/8/12 Hrs for Indoor Seedlings Germination (Lifetime Free Bulb Replacements) - White

Updated Review: Following on from leaving the review below, Sansi reached out and offered a replacement as they suspected the product was faulty. The replacement arrived super quickly (next day!) which was awesome. As soon as I unboxed it and started unwrapping the arms I could feel a big difference. The new one has a much stiffer clamp and much more rigid arms. IMPORTANT - goose neck lamps almost never offer fully rigid posing and generally have a range of stiffness that offers a variety of “good” positions they hold in. The faulty lamp arms had almost no “good” range, whereas this new one allows me to have the lamp arms held securely in a far greater range of positions. And most importantly, they don’t slowly slip or swing downwards now! The clamp has foam cushioning to prevent damage to surfaces which I suspect partially contributed to the faulty lamp slipping (though the pressure exerted from the faulty lamp was less than the new one). The new one holds far far better, though I will be affixing some silicone across the ends of the clamp to help with its security. Changing my review to 5 stars - the new lamp does exactly what it is meant to do, the bulb quality is fantastic, and I’m really grateful for the support offered by Sansi. Original Review (1 star): Really struggling with this lamp. Had it a short while now and after an incident with it today I thought it fair to write a review. For some reason Amazon isn’t letting me contact Sansi through here to raise it with them (sorry Sansi). Don’t get me wrong, the bulbs themselves are great! I’m not sure if my lamp is just a dud, but there’s a couple of issues I’m having with the actual lamp: 1) The clip/clamp on mine isn’t terribly strong, so much so that if clipped to a vertical surface then it will verrrrry slowly slide down. I’ve tried it on surfaces of differing widths - same problem. I can only get it to clamp to a horizontal surface and stay put. 2) The 3 posable limbs have a very limited range in which they will stay put. I can have all 3 arms standing upright with the bulbs tilted in the direction I’d like, but as soon as I lean the arms in any other direction, they with either fall/flop forwards/down or swing back towards the upright position. Sometimes, they will just swing downwards on their own (more on this in a minute). This makes it really difficult to actually control the direction and of light and the distance from the plant 3) The bulbs get VERY hot. Not a problem in itself, I’ve got a few similar bulbs and know this is expected. The problem is that when this is coupled with the above issues, there is no way I can safely/comfortably leave these lights set on a timer when I’m not at home (or even just not in the room). I’ve had the lamp on this afternoon and it seemed secure in place. Went to go make some food and put a load of washing on and when I came back one of the lamp arms had swung downwards and had left the hot bulb pressing into the substrate of one of my plants (luckily it wasn’t on the plant itself). Another arm had swung against a wooden shelf, and only the third remained in place. Due to the elevated fire risk, risk of cooked plants, I may not be using this lamp again, not at least until I can permanently affix it and its wiggly arms in place somewhere in which I don’t need any flexibility. My other Sansi products are great, and as I said, the bulbs themselves are fab…it’s just the actual lamp causing me grief which is a real shame. There are plenty of great reviews here so it may well be that I just got a faulty product, but it could also be the case that the product design has changed for the worse or perhaps other reviews have been left prematurely and not updated. I don’t know, I’m hopeful mine is just busted.

This grow light is fantastic – very bright with a full spectrum that’s noticeably boosted my seedlings’ growth. The single brightness setting is strong and consistent, perfect for indoor plants. The gooseneck arms are sturdy yet flexible, making it easy to position the light exactly where needed. Build quality feels premium, and the clip holds firmly without slipping. It’s a compact size but powerful enough for a small growing area. The lifetime bulb replacement offer is a great bonus. Simple to set up and works flawlessly – highly recommended for beginners and seasoned growers alike.

These are very good quality. Very solid, and very good value. But they are so heavy and stiff to set up and to clamp it on to suitable surfaces (2-3cms). I'm 74, female, and still have good strength in my arms, but not so much now in my hands. As such, I found it extremely difficult to open and fit the clamp on. After many attempts, when I did finally manage to clamp it onto a shelf and position the flexible arm, it was too heavy to stay up, and pulled the lights downwards and out of position. It seems they need to be more upright in order for the weight not to pull it down. Regretfully, I had to return them.

Works very well, not only is the orange plant surviving but there is new growth and flowers. Last year the lemon plant was nearly dead by now. I only have one citrus plant at the moment so am only using one lamp. It is only on for 3-4hrs most days.

Very pleased with this Grow Light from SANSI I have been using the standard purple light (red & Blue) for my Bonsai and decided to replace it with this Full Spectrum light. Really strong clip for fixing to a table or in this case, an overhead bar. I struggled with the clip as it is so strong and had to get my OH to put it in place for me. The lights have gooseneck fittings which can be bent easily to any angle. The (two) lights in this case, give off a strong Day light with a warm tone. I am very pleased with these LED Grow Lights. This particular model doesn't have a timer and so I attached a Timer switch to the plug. Happy to Recommend

Simply the best grow lights, a very strong grip to attach so you can direct the light wherever you wish, these are very good bulbs, they come with the promise that if a bulb fails they will replace it upon request. The bulbs do get quite hot, not bursting into flames or smoking, but very hot just be aware Each light has its own switch. These are very sturdy, if you are looking for grow lights theses really are the best. I more than happily recommend these Sansi lightbulbs and holder

I love these lights! They’ve completely revived my once-sad succulents that weren’t getting enough sunlight from the windows. I was a little hesitant to buy them because of the mixed reviews, but they turned out to be excellent. The lights are powerful and have really saved my plants this winter — I’m seeing lots of new growth and healthier leaves. My only small gripe is that they don’t come with a wire cover, but that’s just nitpicking. Overall, these are wonderful grow lights and absolutely worth it! Also just to note - I’ve barely noticed any difference in my energy usage with them. I unfortunately have a pre payment meter for my electric and has watched it like a hawk - maybe a few pennies difference everyday.

I really love the quality of my sansi set up which now has meant that my Monstera has sized up the leaves without getting too leggy. The down light element also really highlights my plant area in my sitting room providing a beautiful environment with better lighting than I had before. This means that my plant area which I love so much is highlighted even better when you walk in the room as well as the plants receiving the optimum lighting requirements. The clip element is great as it means that as the plant grows I can adjust the way in which it is shining on them. Great quality and I also registered by email to have replacement bulbs if anything goes wrong so good customer service as well.
