I wish I got this $29.99 Courui 12xT6 because I would use it as a XHP host. I just got my XHPs from Mouser today and don’t have a host for them. 
This has been discussed in the Cree XHP70 up to 4022 Lumens and XHP50 up to 2546 lumens - Multi-die leds thread.
That Tangspower T88 looks like this SkyRay 16T6 with a 99mm head and is 6 volt 2S3P.
Remove those XML LEDs and make it a quad XHP.
The Courui 12xT6 should have enough room for Triple XHPs.
