Re: Does anyone use indandescent GLS anymore?

Don't use them in any significant numbers for general lighting now. One outside in a bulkhead, an architectural lamp over the headboard in the bedroom and that's it. I do have quite a collection of lava and glitter lamps though which will only operate correctly with incandescent lamps. So there's a ...

Very interesting. Sylvania do a range of them too by the looks of it in 'Frostwhite'.

Re: SRS vs Quick Start

They both should be reasonably easy on the tubes. Quickstart probably being the slightly better of the two as it relies on filament heating alone for starting, so there's no risk of a cold start.

Re: SRS vs Quick Start

I've probably got one you can have Zel! I could do a side by side comparison video too, I've got 4' 40w battens with both types of gear. There's not much to see with quickstart, tube fades into full brightness over about half a second.

Re: SON/MV compatability

That'd be some overload on 50W MBF though, Rich, or do you mean 80W? 70W SON runs at 1A and a 50W MBF runs at 0.6A.

Re: What Colour is Northlight?

Oh hold on, I've cocked up! Northlight doesn't have significant UV content, I was thinking of Artificial Daylight. To the eye the two look almost identical though!

A very lovely colour, perfect for a windowless office!

Re: What Colour is Northlight?

I'd recommend it! It has a fairly even spectral output plus some UV, designed for colour matching. Certainly a colour I'd recommend, 6500K with a CRI in the 90s!

Re: Starter characteristics

Hahaha! Has it got the right starters in it? Sounds like they're not staying closed long enough if the thing's flickering like hell, and the tubes will be cold starting! Not good.

Bad news! There are a few smaller companies making them, and the two that I've seen the most of are ERC - made in Italy and Electrostart - made in Bulgaria.

I'd also go with PL-C for a domestic install! Cheaper to run, instant light, lamps more easily available, range of colours available, improved colour rendering!

Hah! PFIs never offer value for money! Things are beginning to change here as all the lanterns are being replaced. In some areas it's been completely and I think it's a lot worse. Especially in the fog! You don't know if it's a car coming round a blind corner or just a street lantern as they're both...

Fair enough! I wouldn't want to be reminded of school, seems like the worst thing in the world at that age! :P

Yeah it's not bad, looks clean, simple a modern. At least she wasn't tempted by those things with bits of crystal and tat hanging off them that take about 20 capsules!

Re: My last T8 batten`s days are numbered!

Bugger! She wouldn't come to a compromise with a colour 82 lamp and opal diffuser? :roll:

At least with a fitting like what she's chosen there should be a reasonable amount of light still! That's assuming it doesn't take 10W G4 capsules or something silly.

Colour 20 (Philips colour 33) is the standard halophosphate 'daylight' colour, 4300K with a CRI of 67. Colour 25 is halophosphate 'universal white', 4000K with a CRI of 73. There's little difference between the two colours at a glance, colour 25 offers slightly improved colour rendering but with a s...

Re: Linked out cathodes on fluorescents.

Well, the only two real problems could be starting difficulties and excessive wear in installations with short switching cycles. Providing the circuit can start the lamps it won't be much different to the 'Instant Start' circuits used in the US where only one conductor goes to each electrode.

Re: How does this work???

A layer of dust, dirt or moisture provides a conductive path along the outside wall of tube which can cause starting problems in starterless circuits. Take it out, clean it with a damp cloth, dry it and if possible spray it with silicone spray and buff that off with a dry cloth.

Re: Is 2 x 40 watt more efficient than 1 x 80 watt

2x 4' 40W is brighter at 6100Lm for a white lamp, a single 5' 80W produces 5750Lm. The 5' 80W is less efficient by its self but when you factor in the losses of two 40W chokes (12W each on average) it works out better to use a single 5' 80W lamp. There's also slightly less light lost in a single fit...
