Actually nobody has proven boring the reflector would help in gaining throw number yet, but just a guess, since many de-domed lights perform better after position the LED higher into the reflector.
relic38 obtained 367kcd without machining on the reflector here ; ryansoh3 has modded his X6 but few emitters have failed here ; and 18sixfifty has bored out his reflector base completely and has improved throw here , but he didn’t measure the lux reading though.
