The reason I asked is because I kind of want an affordable BT Shaped 400W mercury lamp, So I guess my best bet would be to get a Sylvania.

Quality is worse...they take what seems like forever to come to full brightness. I had some clear ones...ended up donating them to the ReStore...

Ordered these tubes from eBay for 14,50€ total since they’re aperture type and i always wanted one, but they’re /52 are they biribulin tubes for phototherapy? or at least the same color?
They’re TLA 59D25/52 FA45, does anyone know the specs? thank you very much 

Found on Flickr. Sorry, don't remember who uploaded this.

After weeks of being somewhat inactive, I made a deal with Francis and today met with member fluorescent lover 40 to pick up more SOX luminaries along with an uncommon M-400A variant.

I have tons of stuff to share, but interest here isn’t high enough to really post them unfortunately. But that’s what I’ve been up to.

Yep, this forum has become quite dull...

Well this was Friday, not today, but it's still hurting so it counts 
Managed to slip in the rain at the top of a flight of about a dozen steps at Little Venice, and went crash bang OWW.. 

Gashed my leg open and let some of the 'ed 'tuff out, it's ok-ish now, but still yells a lot 

Not done it as yet, but we're hoping to get to Westminster and take some piccies of the gassy lampses.

Update- the shop said 400w MH or HPS can be run on this ballast.
