Do you know what's LED could replaceing the e10 original bulb? It is a waste to leave it.
First and foremost, welcome to CPF, amy852! :wave:
Waste to leave it, you say? E01's LED/driver combo is dated but still well worth its salt, both reliability- and efficiency-wise.
Since E01's driver is voltage-regulated (there's an old reverse-engineering thread on CPF!), one should make a near-perfect match with a new LED or adapt the driver itself, and that's the probable reason why there aren't many LED swaps. I've read of neutral and red LED mods, if you want to find those you can use CPF search form (keywords: E01, neutral, mod, red LED, swap, etc.)
Cheers
