I run Voost Led throughout now.  For everything.  They have 350-450 nm UV as standard. So it's always on.
I've gradually replaced everything for Voost, so one in the 2 x 2 for veg and two in the 2 x 4.     The value for money is incredible and they are bombproof.
 
UVB is 280 -315nm
Only needs to be run for a few hours a day last 3 weeks flower. 
I'll try and have a listen later cheers. 
From what I can find, UVB LEDs are quite expensive I found some 280 and 300 nm strips with a dozen LEDs on them, pulling about 30W... £1500!!!!!
Yup, £1500.
I think this is why LED companies sell T5s alongside the led units as it's more cost effective for everyone. 
Did you buy your UVB direct from Migro 
@Treetrunk ? WHat were the import costs like???
