A defense bulb or a prosecution bulb ?
None, we have a 10 year backlog so some time in 2018, but if it's urgent you just provide a packet of chocolate biscuits and sweets.
What if it is not a bulb and instead it is a tube light?
and no one say whats the difference.
its the same difference as a PC from a MAC.
We don't change bulbs. We forensically duplicate the bulb via a USB attached PhastBlock Light Blocker and then perform an analysis of the duplicate.
Once the analysis is complete we produce a very detailed report containing many facts while carefully avoiding stating any conclusions (such as if the bulb is actually burnt out or not).
Don't change the bulb, just write a report implying (with no evidence) that a malicious third party hacked the bulb.
