Bulbs or LED Bulbs?

Hi all

I order 10 T5 leds for my Rainbow Riches - Dublin Yer Money, just to try to see how they looked

I replaced 10 blue bulbs for 10 T5 LED bulbs but in doing so a few of the normal red bulbs (about 5), blown, do I have to replace all of the bulbs to LEDs or am I using the wrong ones.

Any help would be great

Thanks!

I ment LED bulbs not blubs!!
