i have 5 light ceiling pendant lights which takes 5 large pendant bulbs. iam using éco bulbs. Have had this light for 3-5 years. At first got bulbs to fit - no problem, but now all large bayonet bulbs are Loose in The holders and do not make proper contact. Is there springs inside The holders to make The push up and twist mecanism work?, and if so can they be made to work again or do i have to replace my lights?. Would be grateful for feedback
