These are new white reflectors, with a few small imperfections/blemishes on the outer case, so they can not be sold through the normal supply chain. This does not affect the performance in any way. Please see the main EM230 page for more details on performance and mounting options.
There are also some orange cases available, these have the old wording on the cases.
EM230BR New 2nd
Seconds are units that have blemishes on the outer case, we are therefore able to offer them as seconds.
