No light inside, not as spacious as it might seem, the interior oven has a v shape to it and the rack is also v shaped however the baking pan and other conventional pans are not designed to use the v shape interior. The oven doors also open outward and both simultaneously so that needs to be taken into account as well as the oven getting really heated outside so it has to be accommodated carefully taking into account the short cord too. Overall gets really hot so food has to be watched and cooking temperatures adjusted accordingly.
