Lumatek Zeus 600 Pro

Hey sorry to bump an old post, but i am confused on something.
The Lumatek Attis 200w/300w/300w PRO use LUMLED diodes, but the bigger fixtures such as Zeus 600w use Lumileds.
What is the difference between LUMLED and Lumiled?

EDIT: Sorry i didn't read the whole post. So if i understood correctly, LUMLED are Lumatek's custom diodes, but Lumileds are Phillips diodes?
Are LUMLEDS reliable? How do they compare to other popular brands such as Samsung?

Ive been running this led since april with no problems at all.they have a little far red which the gals stretch abit but get awesome penetration and nice buds right down through the canopy .im consistently getting 2 p in a 5x5 but only using 5x4 area.thats about the norm....theres plenty room for improvement too.the right strain and grow style could yield 3p no worries.
