Re: SON-I Snapstart Lamps - 2 Stage Run-Up?

Could each lamp that was still firing, (causing its ballast to inductively collapse), have created some sort of momentary voltage drop in the others to make them extinguish, leaving the, (now), heated start coil to remain open for a while, until it closed again to re-heat itself, and start the proce...

Re: [repost] Amber minor restoration project!!

Its a shame you can`t make Kevs meet?, I have an original Acrylic bowl for these, (its what the early lanterns would have had), though not the original `squarer` Amber one, its totally without cracks. However, you`ll notice its got paint on it!, its what I use to sit Beta 5 canopies on to paint them...

Re: [repost] Amber minor restoration project!!

Shame this didn`t have the original ballast in it, it would have been the old SOI beast!, I use to have one, but it failed on night, with a tiny popping sound, and a little wiff of smoke from the terminal block :cry:

Re: The End Of The CFL

I have to say though, although you can still get CFL, I wouldn`t miss them a bit if they disappeared, cause lets be honest, the LED equivalents are far superior to them anyway!, although, they were an engineering marvel, to be able to take fluorescent tube technology, and miniaturise it the way they...

Re: Short Time Running Of Fluorescents

GE say that discharge lamps need at least a 10 hour run on each switch on, less than 10 hours reduces life by 25% for each burning cycle. Having said that, I don`t think it will harm fluorescents with just a half an hour run per start, and with the use of electronic starters to `soft start` any tube...

Re: Does anyone use indandescent GLS anymore?

GU10 halogens are a bad idea, the 50s run far too hot, and their not the best quality either, failing within a year!, 35s and 20s would suit better, but with GU10 LED prices falling like bricks, (Wickes`s own ones are very good, and its what I use at work along with MiniSuns), is the best option.

Re: Does anyone use indandescent GLS anymore?

I have 2 x 40watt candle GLS in the cooker hood, (although rarely used). 3 x 15watt Pygmys, one in the fridge, one in the microwave, and one in the central heating cupboard where the control clock is. Then 2 x 60watt Halogens in the `flame effect` portion of the fire!, so a total of 7 in use, (on an...

Re: LED Flood lights / Easy Repair

I agree, the diodes are not the problem, but you should be able to get drivers `off the shelf` for these today!, then lighting can go back to old school, but instead of changing a lamp and ballast/ignitor, it would be the diode and driver. Thats my only grumble with LED at the minute, you can`t get ...

Re: Thorn SRS 6ft Fluorescent fitting problem

MCFE tubes are coated with a transparent water-repellant silicone coating which prevents the formation of a continuous film of water on the glass. On starterless circuits the starting voltage is dependant on the electrical resistance of the glass surface and is at its weakest when this resistance is...
