If you can afford go with 2 new SP-3000, I have 2 other leds from other brands with samsung diodes and it's just another level imo, that's why Mars Hydro did very well to upgrade do them.
And don't get me wrong, the SP-250 it's an amazing light, very happy with mine but I think growers will notice the difference from the epistar to samsung diodes.
Time will tell, I've got time to figure out my r spec light. I literally just started my seeds for next grow this week, so 2 months time
