Re: fluorescent tubes

Hi there!:-)),
No it's not. Especially if you consider to use 1 TLD/930 and 1 Lumilux/72-965:
3000K + 6500K => 9500K/2= 4750K not so bad!;-)

yes, I know 'biolux' tubes from Osram since 3 years ago. They work pretty 
well. I'm European (Italian) and I've always used fluo tubes with CRI>90. 
The lumen output of Biolux is exactly the same of the other Tld90's tubes. 
That's to say lower the the TLD80 series, less bright. Which leads to the 
consequence that you should put at least one more 30W tube, to achieve the 
same lumen output.
