This has changed with 9.5. You can now use any kind of object for a light, not only the preset shapes. For this tutorial you might like to use an Area Light with shape set to cylinder.
Take a look at the 9.5 addendum for more information.
Edit: Small correction, use the Line shape instead of the Cylinder shape, only line area lights support visible light.

Don't suppose anyone can give me a few pointers on steps to take to do this?

Im struggling..

Really Appreciate it

Well, unfortunately a cylindrical arealight will not help you in this particular case, since they don't support visibility (at least not the fuzzy kind of visibility you're probably looking for)

SO, I would suggest you use a parallel spot instead.

Add a light object, and set its type to "Parallel spot", activate visibility. On the 'visibility' tab of the light AM settings, switch off the top falloff option, activate 'use gradient' further down on the same tab and play around with some colours there. The 'outer radius' value on the details tab will let you adjust the thickness of the effect, and the various falloff and distance options on the 'visibility' will take care of the rest of your tweaking needs.

thats a damn good point.

why have plain old tube lights gone? i used these all the time for my archi neon lighting. ever so easy to adjust and use.

An Area light set to line will work exatly as a tube light, only more flexible.

i hate to ask pain in the ass nube questions, but how do i emmulate my beloved tube light (neon style) with a line area light?

never mind, figured it out :p

but how is it more flexable srek? it looks allot more finiky to control than tubes lights were.

i liked the near/far clip options, which i dont get now. and of course, near/far clipping is different than the fall off types.

also, i just created a curvey spline. i put this as my light emmitter, but the visibility options are dissabled. why is this? same difference as a straight line isnt it?

Yes, you are right, Near Far clipping is not available with Area lights, but the new option to use a gradient instead of an inner and outer color adds a good deal to the functionality.

Well, I must resurrect STRAT's question. I selected Area Light, selected Area Shape:Line. I tried a cylinder & cube (both C'd) and tried dropping these, individually, into the Details tab:Object box. They were rejected. Pages 9-17 of Add'm9.5 offered little help. If a curvy line, a la neon, is wanted, use Sweep Nurbs and Line?

If you have set the Area Shape to "Line" the Object link field is grayed out. The link field is only available for the Area Shape option "Object / Spline". With that option active you can drop either polygon objects or splines in the link field, but no parametric objects.

Ok, I'm worse off than I thought. I have not figured out how to use a "Line" Area Light as a tube light. Could you give a few more hints? Thanks.

nycL45 - i been making neon for years in C4D, perhaps we should get a neon thread going in the lighting and rendering forum?

just done these as a test -

Very nice, STRAT and do take the lead, man. If I can lend a hand, let me know. For sure, we, the peeps, will learn a lot from your thread.

ok, got more time tomorrow, i'll start a simple neon thread :)
