It all depends what is inside the light itself and if any components are 'standard'.

Certainly I'd have no objection to fitting a larger heatsink if required.

I do object to having to cycle through low and SOS just to turn a light off though, so possibly a different driver and/or switch.

Luckily, I've been able to remove unwanted modes in the past by modifying boards and switches

Though one patient did die on the operating table

SOS aside, the DX P7 cycle light looks VERY promising and costs a lot less than the home brewed P7 housings available.

And as some of the MTE P7 torches have no more heatsinking than the DX cycle light, there's no reason why it shouldn't work ok standard. (I'm not picking on MTE, I've only taken 2 makes of P7 torch apart and the heatsinking on my Aurora is much better).

Anyway, I think DX are going to sell a lot, both to people who are going to use them standard and people who will use them as a housing for their own project.

It looks like a great light to me (P7, Li pack, charger) and it's a pity people will rubbish it before it's had a fair trial - especially if they are in the 'custom housing' business....
