Warm white, 9 lumens(matched to 44/47output), bubble top to look like a bulb, 6.3VAC non polar.
When we started testing LED's we just didn't like what were seeing, so we made our own. Are these special? All we wanted were bulbs that would last forever and not change the classic look of our machines. These did the trick. Color matched to 44/47 bulbs, these look great under plastic, or anyhwere you need to swap a bulb.
