Some obvious ones:&lt;p&gt;Defined and validated environmentals (temperature, voltage, and in this case pressure).&lt;p&gt;Qualified components — capacitors chosen for lifetime rather than shaving a cent, perhaps avoidance of MEMS oscillators with helium sensitivity.&lt;p&gt;Failure analysis. Low and understood probability of fail-unsafe conditions (short circuit), mitigation for those risks, fume-proof and fire-proof PCB materials to protect the sealed environment in case of failure.&lt;p&gt;Redundancy to handle failures anyway. Multiple independent strings so that single-point failure lead to partial loss of lighting, not all of it.&lt;p&gt;Load ahedding, eg dropping all but one string at a known voltage above minimum voltage, to save power for other more critical loads during system failure scenarios.</text><parent_chain><item><author>tredre3</author><text>I personally believe using mass market makes sense.
