Can i mix HPS with cree leds? New room building medice

Hi hello

I got a fresh new nice philips HPS 600W
i buy new ones couple times.

i have run my about 3months and then change to new.
This is stupid.
They last about 16.000hours i read now
Is this true?

Anyway i got couple of these in good shape i believe.
Today i also got new big huge nice 150mm reflector, huge one 70cm + . professional

I need have my HPS 600w for a while now.

I start building bigger room indoors now soon.
I like what i read about the True cree cob leds.
I dont have money buy all 8 of them now.


I will buy two of them soon. can i mix them with hps ?
The company is US based , this is the real cree / cobs.
Expensive

ALSO Philips HPS , how many hours does them make average?
I have digital adjustable ballast.
I never run them at 660w . even if this is possible.
I go 600w max

crazy english, sorry.

i will use HPS system for vegging only in future i buy 600w MH bulp.
I will veg outside this special growroom.

My philips are the red ones .
And the cree/cob i choose the low K, flower

My english is so bad , sorry again.

Please help

You most definitely can. I grow under a mix of cobs and hps.
