| If your aren't from the US or Canada, so I think that the lamp may not be compatible to your fluorescent ballast. American 40-50W MV lamps, are low voltage lamps, designed to be operated on 120V chokes, and as such, they have a lamp voltage of 90V. The european 50W MV lamps, designed for 230-240V series chokes, and as such they have higher lamp voltage. I think that on your 36/40W fluorescent ballasts, european 50W MV lamps would operated correctly, but the lamp you want to run, which is a low voltage MV lamp for the american market, it would be underdriven.
E26 or Medium, is smaller than E27 and have slightly different design, and I don't know if they are compatible with each other.

Please forgive me if my choice of my words looks like offensive, while that isn't my intention.
I only working with the international date format (dd.mm.yyyy).
I lives in Israel, which is a 220-240V, 50hz country.

| Dor, 90V arc seems unreasonable high for 120V supply..
The European 50W lamp is rated 95V 610mA. Some lamps with virtually the same arc voltage are 18W and 26W PL-C, rated 220mA and 320mA respectively. So the 50W lamp would be a little underpowered if used with 18W PL-C + 26W PL-C ballasts in parallel, or a little overpowered if used with 2 26W PL-C ballasts in parallel
E26 vs E27 do fit for the most part, but the skirt of the socket may not be compatible i.e. lamp glass might touch the socket skirt when it is screwed in (which may lead to cracking of the lamp), or it might prevent from screwing it in altogether

| It does not state that the ballast is a choke. With HX ballast the arc voltage can be chosen freely, and then this lamp is very similar to the European lamp

| The 50W is exactly the same rating asthe European (0.6A, min 200V OCV).
The 40W is the same lamp just driven at 0.47A.
Indeed, either current could be easilly assembled from multiple fluorescent chokes...

| fluorescent ballast will drive lamp at 430 - 460 mA m
But it would run much better if u use a 39 watt MH Ballast . But that even rare to find in magnetic ballast.
If u access to 240 volt a 58 watt fluorescent choke
Is much better choice.

No LED gadgets, spins too slowly. Gotta love preheat and MV. let the lights keep my meter spinning.
