Very bright. Average quality but a very good price. Just be careful that you don't kink the strip as they are a little fragile. Very happy though. :-)
Where to begin I chose Swiss Post but agreed to change to Yanwen on the seller's recommendation which resulted in a full 2 month wait compared with the 2 weeks it took for the drivers and channels to arrive. The "white" LEDs are practically blue and they are possibly the worst quality strips I have ever seen. Just about every single solder joint has failed now and the waterproofing had to be cut each time to do so and could not be resealed. If you do end up getting them, make sure to dissapate the heat properly as the LEDs burn up in minutes if the crappy adhesive isn't holding them to the aluminium. My advice is to spend a bit more and save yourself the hours of repairs this junk will require.
