I just been down the town and noticed that they have sets of 120 leds for Christmas trees for 12.99.
They were all blue leds with caps added to change the colours.
It would be real easy to remove all the caps and add these 120 leds to my grow room and see if it made any noticeable difference.
For only 12.99 seems to be worth a try to me,as a side lighting option only though
