sunpulse bulb anyone get good results

hello out there just seeing if any one uses or has used the sun pulse bulbs
i have a 2 400 watt systems going now with 1 grozilla type hood with
one hortilux hps bulb and the new sun pulse mh 3k bulb
just want to see what people think of these bulbs as there $20 each
at the grow store all of them 250-1000 watt so just looking to stock up

Did you end up buying the sunpulses? i would love to know how you would compare the two... I'm actually trying to decide which one to get right now for my indoor grow
