Hi,

Your upgrade path will depend on whether you want to keep the 6100 version clusters or want to use the newest 6300 clusters.

My recommendation would be to upgrade all 3 fixtures to the 6300 clusters because these will provide you with the same led configuration found on our Mitras LX 7206 fixture which includes a UV channel.

In order to upgrade 1 fixture, you will need to purchase 3 packs (each pack comes with 2 clusters).
These can be found here:

For 3 fixtures, you would need 9 packs.


NOTE: You may want to also replace your HV LEDs, these can be found here:
