This builb is only 5 watts so keep that in mind when choosing a plant and lamp location. Best in small lamp and for a medium to small house plant. Its not insanely bright but good enough for that use.

I only removed a star because the items box was in ROUGH shape, the bulb appears undamaged however.

The Barrina grow lights arrived earlier than the time was expected thank you ! I like the color it dose not turn my room bright purple and looks nice.

If you need lots of light, this might be the product for you. But I would advise measuring your grow tent (or area) carefully to verify that this light, which is fairly large, will fit your space, and that you have enough headroom to keep the light away from your young seedlings.

I did not measure before purchasing this light and really should have. Somehow, I missed the fact that the unit is not a square but a rectangle; I must have seen that one dimension is 22 inches and assumed from the picture that it was a square, 22x22". It is NOT a square and in fact is 22" x 28". Since I had a grow tent that was 2 feet on each side, the 22 inch dimension was great but the 28 inch did not fit, and so I could not use this light at all.

I ordered a larger tent, 4 feet on a side and about 8 feet tall. This of course could accommodate the dimensions of the light bars; but I missed the growing season and only recently got ready to start growing again.

This light unit is made from several LED bars that are mounted on what appears to be aluminum, not doubt to dissipate heat. The several LED bars are connected together by fairly hefty steel bars. The power unit is mounted on the top along with four metal loops that are used to attach the support system which consists of a bundle of 4 steel wires that are connected at the top to a carabiner. The carabiner in turn connects to a "yo-yo" type adjustable length lanyard that is commonly used in grow tents. The cord on this lanyard is a thick, strong woven material.

The power cord is long, approximately 10 feet, convenient when wiring up the grow tent. The power cord has an in-line power switch which is on/off; there is no adjustment to control the intensity of the light .. it's on or it's off. Speaking of intensity, this unit puts out a LOT of light and you will need to control how much light reaches your plants by moving it up and down using the yo-yo lanyard. The vendor has recommended that for germination and seedlings that you need at least 36 inches of space between the lights and the plants. Given how bright this light is, I think that an even larger gap might be appropriate. Once your plants reach maturity, you will likely love the high intensity, but you need to treat the youngsters with care.

Another measurement that you need to consider if this unit will work for your growing area is the vertical space requirement. The support system of the light, with the lanyard in the 'all the way up' position will require anywhere from 24 inches to 28 inches, depending on how you configure the steel support wires. This means that you need about 2 feet from the top of your grow tent/area just for the light's support. You need to take this space requirement into account to determine if the lights can be kept far enough away from your plants to avoid "light burn". You also have to consider how much space is left for you mature plants, so that they don't grow too close to the lights. Now there may be alternate ways to mount the light in a grow tent such as lashing it to the top supports in the tent; but I have not considered this in this review, and only address the mounting options that are in the kit and discussed in the product manual. Mounting the light very close to the top of a tent MAY cause a heat issue since the power unit is on the top of the lights; I would only advise this mounting method if you are VERY sure that you know of amount of heat created and you have a method of dealing with it, to avoid a fire.

Included in the kit, in addition to the lights, are two metal bars with screws, a screwdriver, the yo-yo lanyard with carabiner, the support steel wires, also with a carabiner and clasps that to attach the wires to the light. If you have misplaced the instructions, as I did, for the unit I can remind you that the two extra metal bars and screws are used to attach multiple of these units together; if you have only one unit, then the bars and screw are not needed.

I will surely use this light during this season's growing; although I may start my seeds with a lower wattage light source and then move them under this unit when they are old enough to handle the very intense light provided.

Great little light! Price is decent!
May get another soon! Looks like an Angels halo to me! (:

Excellent, I can't stress enough how well these were packaged to prevent damage, very well done. The quality is great and the work fantastic for my indoor plant grow stand. I mixed 6500k with 3000k with these and found amazing results.

Added for flowering. It helped. Happy with purchase.
