I ran out of every day use tubes. Using F96T12/CW philip alto lamp I am using American 110 watts philip alto. RDC end caps removed to reveal bipin endcaps. F96T12 halophospate Cool White tube 4100k, I had to Change the cap To 5.5 uF to reduce lamp current close to 800 mA, so ballast dont run hot cause overdriving the tube. As result the Choke ran cooler properly feeding the correct current for American HO 8 foot lamp. Also my step up tranny ran cooler too. I think u guys need to import American 8 footer to keep those existing pop pack alive, philips or silvania that have removable RDC converter. GE is better tubes of all but u cant change to Bi pin easly. U might have to change value of cap accordingly cuase i am from USA. So have different phase angle of the current. That when a current meter comes in handy.

That looks huge for 8 foot!

Do these lama physically fit the same?
Funkybulb   [31 Dec, 2015 at 11:43 PM]
Yes kev, even our 8 foot T8 86 watt HO lamp will fit

Id like to import a case and use them around a few schools lol

That would be interesting, to see if they survived the trip?

@Funkybulb:
Interesting... so if I change out the 7.2uf cap on mine for a 5.5uf, I could run a 8' 110w lamp without it overheating? (not that I mind the 100w 7-footer which needs no cap, I kinda like it anyway Smile could be interesting to see how long it lasts...)

Have you ever tried a HO T8 to see if it'll light? (I have yet to find or even see one of those lamps locally)

@ xmaslightguy, yes that correct 110 watt HO now in everyday service using 5.5 uf cap. Yes i tried a 8 foot HO 86 watt T8. It lights but it need some expermenting. Like more cap reduction for the 400 somthing mA. I took cap down to 3 uF, it made lamp think it EOL as it cant reach it arc voltage. So T8 HO might be a hard one. BTW it going little bit in overdrive as with out cap it putting out about under 1A

@Funkybulb: I remembered that I've got a couple 5uf 440v cap's sitting around from another test (trying to run a 5' T12 HO lamp on a 5' switchstart ballast, which didn't work out) I think I'll try one of those & see if it works on the 8-footer sometime. Smile
It would be awesome if someone could figure out doing a 8' T8 on switchstart!
