From the LED Tube structure, most people can
get the main factors which effects on the tube quality: LED chip and power
supply. But there’s also another important factor: Aluminum PCB board.
1. LED
chip: For led tube, most factories choose SMD led chips: SMD3528, SMD5050, SMD3014,
SMD2835.
There's heat sink on the SMD2835 SMD3014 LED chips, but no heat sink on
SMD2835> SMD3014> SMD3528>SMD5050
SMD5050 led chips is worse than SMD3528 and
harder to control the lumen decay.
Working hours suggestion:
LED SMD 3528 no more than 8 hours working continuously
LED SMD 5050 no more than 8 hours working continuously
LED SMD 3014 no more than 14 hours working continuously
LED SMD 2835 better heat dissipation than LED SMD 3014
Some choose Taiwan brand led chips and some
choose China produced led chips. Then absolutely caused different prices, also
different qualities.
2. LED
Driver: It’s the heart of led lamps. Can be Isolated driver or non-isolated
driver. Different qualities will cause 1.7-2.5USD cost differ.
3. Aluminum
PCB board: much better heat dissipation effect than FR4 board. This is also an
important factor on quality and price.
Ecosram LED TechnologyLimited high
quality LED Tubes choose Taiwan brand SMD2835 LED chip, Isolated driver and
Aluminum board: High quality and 3 years warranty, also excellent after-sales
service.
