Evening mate.
1. How blue are they mate? If they obviousley emit blue light, it's a fail. If it's more a white light with a tint of blue, it's testers discretion. If I were you, I'd put ordinary bulbs in for the test and then swap them back afterwards.
2. It doesn't matter if one is higher than the other mate. So long as the beam line is within the legal requirements on both sides, it will pass. If they are not within the requirements, the tester will (Normally) adjust them for you.
