My 140 is 72 x 18 x 24 high. If it's 30 high it's probably only around 12 inches wide which would be an odd size aquarium.

ok you are right it is 72 long 18 deep and 24 tall, is my light system ok - or do i need to add

Your lighting is minimal at best for sps corals. A good rule of thumb would be 5 watts per gallon (which you are close too). This is just a general rule, other factors such as tank depth and placement of corals will also dictate lighting requirements. Deeper tank=higher wattage light, so that there is a high par rating (lower par means insufficient spectrum reaching bottom of tank). At a 24" tall, you might be ok with what you have.
