I grow most of our veggies and herbs in our basement, and have two large rooms - one for larger floor plants, and one for seedlings and smaller plants that can be grown on shelves. In the room for larger plants, I have quite a few of the larger Mars Hydro LED lights, mostly TSW3000 and a couple TSW2000.In the room for my shelves, I use primarily T5 fixtures that have been converted to T5 LED tubes. One of these fixtures quit working, so I decided to try this TS1000 to replace it even though the fixture is much smaller than the one it is replacing.Since this fixture was being used on a middle shelf, I didn't want the transformer to be on the light as it would heat the shelf above. So, I removed the transformer and the dimmer and put it on them top of the shelving unit since the electrical cable was long enough. Then I attached the light to the underside of the middle shelf with S-hooks. Once this was done and the TS1000 was plugged in, I found that the PAR level of this light at 8 inches from the light, dimmed to 35%, was the same as the LED tube lights at the same height. What this means to me is that I don't constantly have to adjust the height of the light over the plants - I need only to adjust the dimmer. I also found that this light, though smaller, provides more light for a larger area than the the 24" tube lights. One of my pictures shows this TS1000 next to one of the LED tube fixtures. At the levels they are, the PAR level is the same under both fixtures, and the TS1000 is set to 75%. My testing was all done with a high level PAR meter.So, to sum it up, what do I like about this TS1000 as compared to the LED tube lights I am using.1) Light intensity can be adjusted by using the dimmer rather than adjusting the height of the light.2) Light intensity is much stronger than provide with the T5 LED tubes and can be dimmed to desired intensity from 0% to 100%.3) Multiple fixtures can be daisy-chained so light intensity can be controlled by one unit.3) The new design of the hood for this light extends stronger light on a wider area with this 15" fixture than is provided with 24" LED tubes.4) No heat is generated from the LED diodes. So, plants touching the light won't be burned by heat, although plants too close to the light will get excessive lighting.5) The power source can be removed from the top of the light and is attached to the fixture with a long cable. This can be helpful when the light is used in an enclosed area such as a grow tent. The power source can be place outside of the tent so as not to heat the area inside the tent.6) Since I have quite a few of the Mars Hydro LED lights, and have had great success with them, I am assuming the quality is equal on this smaller TS1000.This light is recommended for a 3' x 3' area for vegetative state, but was tested in a 2" x 2" area. In my opinion, it would be better for a 2' x 2' area at a height of 18" to 24" unless the intensity is reduced by the dimmer. I do recommend this light for shelves or for smaller areas.UPDATE 03/15/24:I like these light so much for my shelves, I decided to buy 2 more for my 4' shelf to replace the T5 LED fixtures I have been using on this shelf. I have added pictures that show this light over seedlings and one of the T5 LED lights over other seedlings. Even though this TS1000 is much higher (15") above the plants than the T5 fixture (4 inches), the PBFD reading is about the same except that this light has better reading at the outer edges of the light. Considering the cost of the T5 fixtures that the tubes need to be replaced with LED tubes, this TS1000 is much less expensive and provides better and more usable lighting for the plants.UPDATE 03/23/24:I have been using these lights for about 6 weeks, and I am amazed how much faster my plants are growing even though I have these lights 15 inches above the plants. Although I don't think these lights would be as effective in a large area, I am ecstatic with the results I am seeing on the plants I have on my shelf. I'm sure I will be buying more of them to replace more of the LED tube lights on my other shelves.UPDATE 4/08/24 for TSL2000:The previous part of this review is for the TS1000. I decided to try the TSL2000 on a 5-foot shelf to replace a T5 fixture with 8 LED tubes. Although the TSL2000 is much smaller than the T5 LED fixture, it provides better lighting at a greater distance for the same space. The T5 fixture uses about 250 watts and must be much closer to the plants to provide the same lighting. By hanging the TSL2000 from chains, it can be kept further from the plants at 75% power using 225 watts for the same usable lighting (PAR). This saves on electricity and it is so much easier to water plants with the lighting higher above the plants. I have added pictures of the TSL2000 and the T5 fixtures over plants on shelves.I decided to try adding another TSL2000 to my 5' shelf that is 2' wide, one to the back of the shelf and one to the front. I decided to try this since the PAR level to the front and back of the fixture was much lower than the center. By setting up two lights on this shelf, the crossover lighting between the two is more consistent with the PAR level to the outside of the lighting. I am hanging these lights from the upper shelf with 2" s-hooks rather than using the supplied pulleys. This allows me to hang the fixtures closer to the upper shelf. I have also set both shelves a 50%. So, I am getting a consistently higher PAR level at a greater distance from the plants and using the wattage of one fixture. I am trying this because plants at the outer lighting of one fixture tend to grow slower than the plants in the middle of the lighting. I am hoping to get consistent growth on all of the plants.The TSL2000 has all of the advantages mentioned in my review of the TS1000, but it covers a larger area. I recommend this light for a 2' x 4' area. Anything larger than this would be for low light plants in the area outside of this space.I hope this review was helpful for you.

Very good grow light for a nice price. Will be buying more in the future if the price is still right.Grows me quality personal cannabis no problem. I use two ts1000's for one nice plant. One light would work but I like large wide plants.I gave 5 stars cause the price is right and they last.

MARS-HYDRO TS 1000 LED GROW LIGHTOverview:A few months ago I bought one of these lights to start growing my plants for this coming spring garden and now I have bought another. These lights are tiny, lightweight and they are extremely bright. You just can't beat it, for the cost. If you're looking for a grow light that isn't going to break the bank, but can satisfy your needs, this is the one!Design:Very attractive design and very functional. The slender frame makes it lightweight and easily maneuverable wherever required. The ballast can indeed be removed, which in itself is a great choice if you need to remove a bit of heat. The overall light looks quite elegant and modern and will suit the growing needs of anyone's setup!Light:The light is very bright, white, and full spectrum. Efficiency is around 2.3umol / j which makes growing anything you want wonderful! The light is slightly warmer with the ballast affixed, but I'm only running 2 of these lights in a space of 3x3 and my temperature has only gone up about 5 degrees. For two lights that powerful, when comparing the light to something like an HPS, it's really not a large amount of heat output.The Cons:There are only just a couple of issues that I found with these lamps. The first being the instruction manual is just not helpful and is hard to read. The second is the balance. It should be perfect for someone who doesn't hang many of these fixtures in a confined room. If you are otherwise, since the lights are so lightweight, the cord affects the way the light rotates. I had to make a rig out of some light wooden parts to make them even and sit straight whilst hanging. The last issue is the adjustable dimmer. While it is nice to have, for someone who doesn't own a light meter it is pretty much a guessing game. There really needs to be tick marks or something stopping the screw from turning with a little resistance to be able to gauge what percent brightness you are on!Final Thoughts:The MARS HYDRO TS1000 is a great bargain light that will accomplish your needs. My one light has been running for around 3 months now with no issues whatsoever. If you're willing to spend a little time watching a few videos on how it all works, then this light is perfect for you!

Excellent product!!!!

I’ve bought 5 mars hydro lights in the past few months building up my grow room, my only complaint is that they go on sale THE NEXT DAY every single time I buy them lol, so mars hydro, I will take a 300 watt 2 by 4 as compensation lol, but yeah these lights are top tier

Nice light

Needed to play around to get the dimmer settings but typically keep it at full blast. Have had it for 3 months now, on almost everyday for my indoor plants. Have had no issues. A good product worth the buy.

I've only been using it for 2 months, but it's been very good. I've only had to use it on about 40 percent of the power, it doesn't get to hot.

Light arrived where I am in Oz Had a tiny bit of trouble plugging the power into the light array, so be aware that the hole drilled for the plug at the side of the unit is a very snug fit. I wasn't pushing it through firmly enough at first, but I gently held the other side of the plug receiver, gave it slightly firmer pressure and it went through and stayed snug in the socket.I find it a little strange that you get more info on this Amazon page than you do the Mars Hydro site, but check their recommendations here for light intensity - e.g. 25% for germination. I've got the light hanging fairly low at present, only 35cm from the top of the plants, so I've got it set at a bit over 15% (checking for about 8000 lux using a phone-based light meter, which is accurate enough).Anyway good product, seems to do exactly what it says on the tin, with a simple, good design with well-made components.

So far so good,all led lights work/dimmer nicely.

I am using the product for more than a week now. A very good product and my plants are flourishing with the full spectrum light. I highly recommend this product.A fantastic customer service from the MARS Hydro team. Delivered it earlier than anticipated.very good lighting for a 100*100 cm grow tent.

All good, fast delivery and works a treat.

So I got myself this package which came with a hanger set. With this going through Prime, shipping was really quick. It arrived within a few days since placing the order!For my initial impressions, I can't say how much I appreciate it coming with an Australian power cable. That saves me from having to look for an adapter (or purchase yet another one). The whole thing was packed carefully. There was ample padding, there was even a padded piece of plywood to prevent the middle from getting crushed or bent or warped.I can't wait to test this kit out!
