Electronic Starters and 8' 100W Tubes - Problems

Postby SuperSix » Tue Jun 14, 2011 9:22 pm

I've been doing some tests today with my electronic starters and 8' 100W tubes. Most electronic starters are supposedly unsuitable for starting 100W tubes below 10°C. I recently got my hands on a couple of LEL Multipulse starters, I wont go into details but they're supposed to be the only electronic starter suitable for the 100W and should start them right down to -30!

Well I've not had much success, popped one in one of my 8' Pop Packs with a 100W SLI tube installed. Switched it on to see the normal preheating phase then... Fzzzzzzzz... Parrpppppppp... Thunk! Tried again.... Fzzzzzz.... Parrrrppppp *Flicker* Parpppppp... and then just as it was about to give up again the tube struck. Sometimes it just about works, sometimes it doesn't and this is at room temperature!

Has anyone had any success with this? :P

You should try getting your mitts on some of the old Thorn Vivatronic 4 terminal starters! These were 8' 100w rated and should work a treat! Not got any myself but if the rest of the ratings are anyting to go by, this'll be awesome on 8' 100w!
I LOVE LAMP!

Dont forget that the fittings i sent you are 125W and have the Shunt capacitor! Try simply linking out the cap! One of the fire stations i look after is completely fitted out with those LEL starters and i have never had a problem they work every time however i have had to replace a few!!

Hmmm I did think about that but on there site it says 'Lagging or leading, standard, low loss or extra low loss' for the ballast types so it should work, in fact it does work now! I don't know why but for some reason they really struggle with a hot restrike, I literally took the existing stater out and put one of these in for the test I did and had trouble, when the lamps start up from cold they do the usual preheat, hum and then strike though! Weird!

Do 125W tubes still work with the cap out?

No problem I had the same problem when I got an atlas 125 warm white tube and it would not start in my 100W 1992 thorn PP until I put the cap in series on the live side and it struck :D

And where is this 125W atlas now BF??. What a lot of people do do with the 8 foot 125W when the cap goes is simply link the cap out and stick a 100W tube in it!

I stll got the tube - I got the tube when I got the BC tube. I store the tube horizontally on my bed so the end does not crack because Atlas tubes can crack at the end when stored vertically on a hard surfaces :geek: :D :D
