Got a question regarding "mixing"
bulbs. What I mean is mixing "new"
bulbs with
bulbs that have about half their useful life left. If it's possible how should the
bulbs be rotated, i.e., two old, two new or three old, three new, etc?
The reason is to possibly save money and cut out the customer complaints about reducing their time to about half once the new
bulbs have been changed in the entire bed.
