Review on Wall-ceiling lamp IN HOME SPO-110 PRIZMA 4000K, 55 W, 120 x 6.1 cm, armature color: white, shade color: white by Micha Bialik (Eagle) ᠌

Revainrating 4 out of 5

The product is good, there are only a few minor flaws.

It is too early to judge, with the changed value of the CS-resistor, 23 lamps have worked for 2 months without problems. Replacing the BP2867F with the BP2867G, in addition to increasing the value of the CS resistor, further reduces the temperature of the driver. I gave it a rating of 4 only because I had to bring the current consumption of 23 pieces of lamps to the TTX rating, for which I had to purchase SMD1206 1R6 resistors and install them in place 1R05, in parallel to 1R2.

Pros
  • Luminous flux / price. The body of the substrate, although thin, is metal. Low weight. Ra>80.
Cons
  • Shimka heats the ballast, which lies directly on the Shimka body. The ventilation system of the driver compartment is poorly implemented. The current consumption is too high - not 270mA as in the TTX for the lamp, but 333mA. The driver heats up to + 90C. A mandatory increase in the value of the CS resistor is required to reduce the temperature of the driver, the LEDs themselves and for a possible increase in the service life of the lamp.
