Depends on how you use your MH. I replaced all of mine with LED’s purchased from a china seller on Ebay. They are the flat 48 LED board style, with a bit of searching I think I paid about $1.50 each. I purchased a few extra just in case, and not one has died The adhesive on them was no good, but that was an easy cheap fix. It has been a while, but I believe all my LEDs pull about the same amount of power as one incandescent bulb. Which really helps extend the battery while boondocking.
As for better; I purchased these as they put out about the same amount of light as the original incandescent bulbs did. Some people will choose a different Temperature (color range) as they like the whiter white, verses the yellowish color.
