I recently installed 4 HALO (Cooper Lighting) recessed lights (6 inch, remodel, IC rated housings. These replaced 2, 5 inch recessed that were of the wrong type (non-IC in contact with insulation). I am using 50 watt (PAR 50) floods in these fixtures and the bulbs have been only lasting a week or two. These HALO's use the pre-attached push in connectors in the junction box. I don't notice any flickering or anything unusual while the lights are on, they just burn out quickly. The lights are in the kitchen and the only thing on the circuit is a few other lights. Any ideas on why thes bulbs are burning out prematurely.
