I find him two big advantages over the CFL (intermittent use for this):
1) instant start 100% yield ;-)
2) life (theoretical) upper ... to see !!!
Because that is the only unknown: the Chinese electronics-such a place over time, especially outside with the change of temperature and humidity: I test !! We'll see ...
Rather excited about this, I again ordered a second for my second stanchion ...
Only defects found: generous dimensions, which are not suitable for all uses, and SMD LEDs unprotected at the base (dust, accidental contact, etc ...)
But in my case, it is not annoying. And so it will work, I highly recommend this article, as the seller!
