My T5 Osram is not very expensive, 4ft is 20+ set, and replacement is 10+, been using it since 2011, the outdoor T5 only change once time tube since 2011 and is on 12 hours a day non stop. T5 tube is not more than RM 15, can sometime get 10+.
I tried replace outdoor T5 with LED, even when is new, is only giving 1/2 the brightness of the original T5, and after 3 months of usages, is time to go into dustbin.
LED Torchlight is good, and light ficture that use CREE LED will be top notch, wonder how many willing to spend these type of quality.
I can relate to that.. I tried replace outdoor T5 with LED, even when is new, is only giving 1/2 the brightness of the original T5, and after 3 months of usages, is time to go into dustbin.

The earlier designed LED lighting didn't last very long because of the design and quality of the electronics..
Go for branded LED's if you're looking for longer lifespan, the quality of the components and design of the drivers have improved significantly.. but whether they're lasting longer than branded fluorescent light still remains to be seen..
Note: fireballs,
you need to use worse case scenario meaning peak voltage = 240V + 6%
LED is a diode so its DC (power factor is a property of AC circuit only)..
back on topic practically the current draw should still be very small,
the main issue here is the quality and durability of the LED and the driver..
