Quad Row LED Strip Lights - 24VDC 3528SMD 146LEDs/Ft High CRI 95 - Brightest Flexible LED Tape Lights - 1,170 Lumens/Ft - 2400 LEDs 16.4Ft Per Roll for Photographic Lighting(White 6000K)

I installed the light strip in a warehouse with 14' ceiling height to replace aged fluorescents. I used the recommended driver because it had a fan and installation is near the ceiling in an non-air conditioned space. I had some difficulty trying to determine which way the switch for the voltage was supposed to be in. Couldn't reach manufacturing company and info on line was not there. However, I decided to go w/being able to see 110v instead of leaving it where it showed 220v, which is position it arrived in. There were no instructions. Upon initial hookup, the lights started blinking immediately; but I adjusted the screw switch and they have worked well since Installed 2 weeks ago. It puts out an exceptional amount of light and the light brightness can be dimmed with the screw switch.

After installing LED under cabinet lights in my kitchen I took this type of lighting system to the next level. I took a pine 16' 1X4 and cut 1-1/8" strip off of it and screwed the strip to the remaining 2-1/2" piece. The sticky backed LED strip is attached to this strip I fastened an electrical box to the top of the assembly and fastened the 24V power supply to the box wired it all together and suspended it from the ceiling with lightweight steel angle and connected it to the existing lighting circuit. Wow, it really lights up the previously dark side of my shop and it seems at least twice as bright as the existing fluorescent lights while using half the wattage.

These lights work awesome. The only thing to watch out for is the amount of power they draw. You need to make sure you get a large enough transformer to make sure the transformer does not burn out. If you need to light up a dark area these will defiantly do the trick. I have them 25' from the ground and we are set for roughly half the max amperage draw and they light it up great.

Compared to competitors products out there, these represent a pretty good value if in fact the advertising is correct. My goal was to build some custom photographic fixtures for flat art copy, and these appealed to me due to their high CRI rating and output. From a color rendering perspective they look outstanding.When I initially hooked them up the output seemed a bit dim to me, so was curious as to the actual output. I hooked them up to a "watts up" meter, and you can see the uploaded photograph. I was getting about 158 watts at 6.5 amps. So, essentially around 80%-81% of advertised specifications. I was hooked up directly to the power supply, so there is not an extra long run of wire. In other words, voltage drop should be negligible. I was still getting a little over 24 V from the power supply.I'm not sure if this is typical of LED's or not, but they're certainly not as advertised. Of course 80% of advertised specifications I guess is close, but I was expecting better.I'll report back later when I finish my project, and do some initial test. It's hard to say if these are a great value are not as I I don't know how competitors products perform or stack up against these. I can say when you start getting close to 200 Watts of LED power, generally things get pretty darn expensive, particularly with high CRI ratings.Overall I think these represent a pretty good value, but this don't expect them to be exactly as advertised.

Pretty happy with this item. I ordered the 16.4 feet advertised as 194 watts. I used 15 feet and my meter says it is pulling 156 watts. Pretty close to what is advertised. They're bright, maybe not 1170 lumens per foot, but they're close.

They do warm up quite a bit, but never too hot to touch. Very, very bright! An 8-foot strip lights up my whole shop.

Less than 60 Lumens per watt? That's lower than a CFL. For what it's worth, I have not purchased this item. Looked at the specs, and laughed to myself.

The strip is easy to work with, the adhesive backing holds well, but the strip does not pull nearly as many watts as advertised - they say 194 watts/strip. My installation uses a little more than one strip, yet at 24V it only pulls 119 watts. I have them in some 2" x 1" aluminum channel to throw some light up above our office cubicles and it looks pretty good.
