4-Pack G9 Halogen Oven Bulbs 25W 230V - Heat Resistant (300°C/570°F) 370lm Light Bulbs for Oven, Microwave, Cooker & Wax Melters - Perfect for Baking, Cooking & Candle Making

Purchased a pack of 4 of these bulbs, arrived promptly BUT there is no mention on the packaging or instructions that they are suitable for use in an oven, which was the whole purpose for the purchase.Point 8. on the instruction sheet states PLEASE USE THIS PRODUCT IN A MODERATE TEMPERATURE AND HUMID ENVIRONMENT?????If they are suitable for a 300+degree oven, surely it should state that clearly on the product packaging and not just on Amazon at the point of sale?UPDATED - bulb now been fitted in oven for 3 months and seems to be doing the job fine - so upgraded to 4 stars.
