The Lamp Room

On my huge list of things to do, sorting my dusk-to-dawn outside lighting is nearing the top.

I've got a Philips something-or-other SON street light with a corner bracket that's probably going to be installed at one end of the house. It's currently magnetically ballasted for 70w lamps. I was thinking about re-gearing it for 50w lamps, but I'm now wondering if it'd be worth using an electronic ballast instead & keep it 70w?

I've measured circa 90 watts being drawn using a new 70w lamp on the magnetic gear. Would an electronic ballast save much over this, and do they drive the lamp at full brightness?

...or (wildcard) should I convert it to pl-t?

42w PL-T gets my vote

My patio Gamma 6 nearly ended up with an 18w PL-C in it instead of an 18w SOX lol

Id stay 70w SON or if you want white just stick a CMH or Street wise in

Surprised the mag is pulling so much wonder how good the cap is. Should drop it down to around 73W on ele gear

90w sounds about right tbh for 70w mag gear tbh. It's what I got when I tested some a while ago.

I was thinking about this again yesterday, I have a few 40w/840 Megaman Clusterlite lamps knocking about. I might try one of them in it. Wouldn't normally be my first choice but seeing as I already have them...

If you already have it than it’s worth a go. Will it fit though? Those things are massive IIRC?

I think it should. The 40w lamps aren't too big, but still bigger than a 70w SON. The 60w and bigger Clusterlites is when they start not fitting in many existing fittings usually

Mag!

Keep it SON! A nice warm, welcoming light.....
