Here is a link to the eBay seller that I bought most of my led lights from. Look through it and find the light with a base that looks like yours. I don't recognize 1457 as a bulb type. note that the bayonet bases come with 1 or 2 contacts.
You might like 36 to 48 1210 leds or 18-24 5050 leds. When you find what you might like, buy 1 or 2 and try them before buying more.
The led color that is closest to incandescent is warm white.
You will find panels and cob lights. Panels are stuck on the fixture while cobs are a plug and play replacement.
