Hot restrikes usually happens when there is a temporary power cut. In this video I want to show you how much time a street would be in the dark based on the lamp type that is used to illuminate it.
from what is seen the high pressure sodium can open faster in relation to the mercury and metal halide lamps, in general it seems that the high pressure sodium wins in everything except the LED and except the color!
I have the master son-t apia plus hg free and it is really very strange, its color is actually like a lemon, very good and long life that reaches 38,000 average life, that is like philips master son-t apia plus xtra at 70w 40,000 hours average life! ! and it has very fast ignition and warm up with magnetic ballast takes only 2.5 to 3 minutes compared to 4 to 5 with electronic ballast only takes about 1.10 minutes compared to 2 minutes but not as efficient as the main sont sont plus with a power of 70w at 6600 lumens and the apia plus xtra 70w which reaches 7200 lumens!! all three models are however very close in performance with LED and LPS, the master son-t apia plus hg free is at 6300 lumens and the color temperature at 2100K, but it doesn't have as nice a color as the 2000K which looks so sweet and golden light in the eye!
@johnjunior5421 I really want a SON-T PIA Hg Free lamp, I found a 250W for a pretty low price and I will most likely buy it because of that lemon color 🍋
