I'll tell you what Paul for home use they're a bargain and ideal at only 30mw.
I know there's no DMX or ILDA at that price but I don't suppose there's anything to stop you fitting an ILDA port. Could make good cheap satellites to a larger RGB.
BTW there are very similar ones on ebay from SHINP for 50mw for the same price.
