Hello
One of my acquaintances asked/helped me to ask this question here.
I have a Fluorescent lamp whose power rating is 17% less than the electronic ballast wattage rating. Details below. I have searched a lot and could not find an exact rating ballast. Further due to pandemic, there are many logistic and closed business issues. So so thats out of option now.
I need to run a Fluorescent lamp rated for 30W(nominal), Voltage-102V(nominal), Current-0.37A (nominal), T8 Size, Bi-pin (2 pins on each side)
Electronic ballast is rated for 36(TLD)/40W, InputVoltage-220V(nominal), InputCurrent-0.19A. 1 Input pair and 2 output pairs (different colors)
I have scoured the internet and read a lot but it seems ballast technology is pretty complex especially with various types of it and it has to be exactly optimal for the lamp it runs. In case of electronic ballasts, high rating causes larger current to flow, decreasing life of filmanent and lower rated ballast will not run the lamp well thus no optimal light and may decrease life too
I found some link very helpful like http://www.repairfaq.org/sam/flamp.htm but being a basic info guy could not find a proper solution.
So in short 4 questions :
1. Can these 2 products be run some way without damaging lamp? Some say just 5-10% variability shd be used as per ballast rating. Here its 17%
2. I found some users suggesting appropriate resistors/incadescent in series. Some asking for delayed switching. Anyone got experience with this?
3. I found that the resistance across the filament of lamp should be EXACTLY same as other old(defunct) lamp with appropriate ballast and i can canabalize it. is it a Correct statement technically? Is resistance of filament a very good way to measure power it needs?
4. If size/diameter of 2 lamps in question (3) are different and measured filament resistance is same, can i use the electronic ballast of other?
Any other solutions?
Thanks. I would be online and quick to reply with details, if needed
