Perhaps the greater issue will be failure of the lead-free solder due to
internal temperatures in new designs of LED lighting which will be intended
to replace a common lamps of significant wattage.

Powerful LEDs also create heat, and when a lot of 'em are fit into a small
package, the heat will very likely be a reason for very short life from the
new technology.

Combining the lead-free solder with the cheapest manufacturer that exists
will probably reduce the projected (dreamed) lifetimes from 10 years to
maybe 2 years.

At about $30 each (and it's likely more of them will be needed to reach
comfortable lighting levels), the greatest benefit these lamps will have,
will be separating consumers from their money.

Anyone that's been servicing consumer electronic gear in the past several
decades has seen the impact that heat has on solder connections, and more
recently, the widespread failures of lead-free solders.

Aren't LEDs also temperature sensitive? Because I had a hot chassis
TV with optical couplers for the composite video and audio, and the
picture brightness & contrast would change slightly when it warmed
up. There were also pots to adjust the couplers.
