Thank you for replying…
I already test out the bulb and it’s still working (100%)
I think ballasts have the problem…
I tried to detach my MH, and it was divided into three parts: capacitor, ignitor, and coil
I think either capacitor or ignitor has problem
With MultiMeter test, socket part shown around 240V
I bought this from somebody and I have used for 1 year now..
And sometimes it showed the flickering problems as you said
Before it stopped working, when I turn on the light on my MH it had buzzing sounds too
But now it does not have any buzzing sound; just little heat from coil parts…
Last question
For 150W MH, only M81 Ballast can be used?
The sites that I posted which parts do I have to buy and change it?
If I have to get an electronic ballasts, which one should I buy(use)?
Also if I have to get an electronic ballasts, do I have to use 250W?
If you have some other suggestions, please reply me back or pm me
Thank you again
