Comparison Of Color Brightness

Comparison Of Color Brightness

Click to view full size image

This is a (fairly accurate) comparison of brightness for colored 4-foot 40w T12 lamps...
As you can see, Red is by far the dimmest (I'd probably have to overdrive it with a VHO ballast to make it comparable the others.) Green is ofcourse the brightest.

Blue & Green are white when off.

What a beautiful setup! I LOVE the colored lamps you have. My favorites are the Green and Blue lamps.

Vintage products are the best! Nothing will ever compare to the quality of old, U.S. made fluorescent bulbs, ballasts, and fixtures.

These are so beautiful , I love coloured fluorescents , I think green has always been my favorite. You mentioned how blue and green (and pink) tubes are white when unlit and red and yellow (or gold) are coloured. This was always the case with coloured fluorescents. HOWEVER , the company I work for use quite a few coloured fluorescents (its a sign company) . Mostly these are Narva 18 watt 2ft T8s . ALL of the colours with these are white when unlit , the colour coming from the phosphor. These are very nice lamps (not quite as nice as old coloured T12s - but nice) - Ill do some pics soon. Also Ive seen other coloured fluorescents that were all white when unlit , including coloured PLs and coloured CFLs . ALSO does anyone remember (or have any?) coloured 2Ds ?? (Those must be a very long time ago !! xxx I really must be getting old xxx!!)

Green I think is my overall favorite as well

@Bluto They do make T5 HO colors (Red/Green/Blue) here which are all white when unlit, the colors aren't quite as nice as these T12's, (but all are really bright)
Maybe similar in design to your Narva lamps?

One company here also now makes a T12 & T8 Orange! but i've never seen them for sale. I would love to get a pair of those ... along with a pare of the vintage/rare Peach tubes!

@rjluna2
Yep LOL .. red being dim like that does go well with blacklight though
(Also red by itself gives a really cool effect - anything red-ish colored in the room stands out ... sorta like blacklight does with 'fluorescent' stuff)

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

I like the REDs the best. They mesh beautifully with BLBs. I have several 3 lamp fixtures set up over my dancefloor/stage area in my shop with either two REDs and one BLB or two BLBs and one RED. I love the other colors too, but those are too bright and "wash out" my dance/party lighting too much. GOLDs are EXCELLENT for keeping bugs away when I have a cookout. I have one fixture set up with three F40/GOLDs installed.
Nice display, but your five lamp hombuilt fixture is still the best!

@DieselNut
I think one of those dimmable 2xF40T12 RS ballasts might be good for when blue or green is too bright LOL I've been meaning to test that out & see how it looks
And gotta agree with you on the 5-lamp'er

I have been thinking of trying that too. I just need to get a dimmer and figure out a nice vintage fixture to use.

I just swapped the Blue & Green here into a dimmable fixture & red into a normal single ... looks great for matching brightness
You'll deff like it DieselNut !!

How that would affect lamp like who knows though (still probably better than overdriving a red would be)

I have definitely got to try that! Can you do a photo or video of it? I do have a very nice two lamp vintage fixture I can use here:

Or even better, these, which I have 15 of:

Thanks! Yes, they are VERY well made! Unique construction and very strong/beefy light.
