Lamp Starting Aid

Lamp Starting Aid

Click to view full size image

As this summer's humidity kicked in this year, a couple of my 40w rapid-start lamps kept having trouble starting. So, I tried an experiment...I coated the lamps with silicone spray and then wiped off. After that, there has been no problem at all!

Above are some random brands I have laying around....I don't know if one works better and don't remember which brand I used. I do recall hearing about Philips using some sort of external silicone coating on their 34w lamps for easier starting (aside from the internal special coatings).

Anyone have any specific info, let us know!

Now a real use for blinker fluid, although the aim here is to eliminate blinking...

Cool that it works !

Yep, Philips lamps in UK had this solution standard and called them MCFE tubes I believe. Exactly the same as TL

Could the residual of Silicone have some kind of conductivity on what you have applied on the bulb?

Pretty, please no more Chinese failure.

As I understand, magnetic RS lamps need a sort of capacitance effect of the tube wall with a grounded reflector for a starting aid. Perhaps the silicone acts as a thin dielectric layer on the glass to help this. High humidity and/or dirty lamps seems to disrupt this capacitance.
