The problem of LED lamp belt for home decoration
First of all, T5, T4, those lights do not consider, the price is high, installation trouble, the effect on the ceiling is not as good as the lamp belt evenly.Flat two, that is a single lamp arrangement, 30 meters, 60, 90120 of the light density. Flat three flat four is double bead and three bead array arrangement, this density can be larger, higher brightness.
Now mainstream lights on the market belt is generally 3528 and 5050, two patches, led specifications for more. Two kinds of LED strip has gluewaterproof seal, single sleeve, epoxy, bare board, the four. These four categories are 220V, 12V, 24V specifications.
You are now using the background color in the ceiling, the effect of a brighter, longer life. It is in the same brightness number and length of beads, 5050 is certainly bright. In theory, 5050 of the brightness and power consumption is about three times 3528. However, the actual situation is that 3528, two meters, 120 beads can reach 5050, one meter, 60 beads of brightness, and the price is almost twice the difference. But 5050 of the power consumption will be much greater in amount, heating power factor of 5050 than 35285050 is much larger than 3528 (do not believe the salesperson told lamp without considering the heat), the heat is difficult to dissipate in the lamp tube inside, if not soon go wrong, but absolutely will affect the service life of a long time to decay, discoloration.
