Hello
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)
Thus lamp power rating is 17% less than the electronic ballast wattage rating. 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. I need to hook up these 2. What are my best options?
I read a lot but it seems ballast technology is pretty old & complex especially with various types 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
So in short 4 questions :
1. Can these 2 products be run some way without damaging lamp? Some say just 5-10% variability is OK in 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
