Fill blank vertical cells with row's horizontal cell values

[ExcellentM]

Have been perplexed by this one today...........Not sure how to execute it.........

I have a column of similar, grouped names. One row of them has a horizontal row of numbers like this

A	B	C	D	E
This Product	1 Light	2 Light	3 Light	4 Light
This Product
This Product
This Product
That Product	4 Light	5 Light	8 Light	9 Light
That Product
That Product
That Product

How do I concatenate the name with the different number of lights downward using the horizontal values as a fill in series? So Far, I have:

=IF($A$1:$A8=A1,CONCATENATE(A1&" "&......................

But from here I am lost............Anyone here got an idea of what i should be looking at as far as a Function to complete it like this??

A	B	C	D	E	F
This Product	This Product 1 Light	1 Light	2 Light	3 Light	4 Light
This Product	This Product 2 Light
This Product	This Product 3 Light
This Product	This Product 4 Light
That Product	That Product 4 Light	4 Light	5 Light	8 Light	9 Light
That Product	That Product 5 Light
That Product	That Product 8 Light
That Product	That Product 9 Light

Thank you

Assuming your matrix is as shown, but this in B1 and drag down.
=A1&" "&INDEX($C$1:$F$1,1,MOD(ROW()-1,4)+1)

Thank you .....it kinda works.....It didn't catch the second set of row values, just copied the same first row down. I just had to fill the series down the blanks, and then changed the formula to this:

=A1&" "&INDEX(C1:F1,1,MOD(ROW()-1,4)+1)

Does what i need.....thanks!
