RSJ and lighting centre of a room

[Kilt]

I wondered is there any options for installing lights in/around an rsj?

I was think LED strip or something like that,  recessed into first layer of PB, but tbh, it doesn’t need to be that powerful a light.

Just token really. 

 

Living Room is 4.4m x 5m and we’re going to have to under-sling an RsJ to stop some terrible deflection in bedroom and bathrooms above. 

We currently have 6 spots in the LR (2 rows of 3 spots) but the Rsj will take up the current position of spots, I plan to put 8 spots back in (4 rows of 2 spots). 

just worried rsj will cast a shadow down middle of room.

Wouldn't it be better to fit two "L" beams in through the joists? That's what we did at our last house. Then you can have a flush ceiling - worst case you have to baton our the plasterboard 50mm.

 

Joists were cut, beams inserted and bolted, batons fitted to joists and ceiling fitted.

Thanks for reply.. I’d love to, but It’s a money thing, however no ones mentioned L beams. Hmm.  
 

Running through joists we have 2 x soils, 2 x 2” wastes, 1 x MVHR and 90% of wiring for house. 
 

it’d mean a massive electrical rewire, and cutting soils to slot rsj in, then pop through rsj. 
 

SE suggested slotting an rsj in 3/4 into span, which would solve drainage issues, but we’d still need 4 rings and 2 light circuits cut. 
Plus joists are bananas, so cutting 3/4 doesn’t fix 1st floor bow. 
In bathroom, we have 35mm fall over 1.8m from wall to doorway. 
 

underslung rsj either in a goal-post or pad-stone seems to be easiest option. 
no rewiring, no joist cutting, levels 1st floor (by 10-20mm), no alterations to drainage, and only a loss of 150-200mm down centre of room. 

its not ideal, but Ceiling is 2400, so not horrific.
