Hi there! Based on your search for 175w incandescent Philip bulbs, I see we have a few great options. The Reptile Infrared Heat Lamps in 75w and 150w would be perfect for keeping your little critters warm and cosy. They're designed specifically for reptiles so you know they'll spread heat safely and evenly. The 75w lamp is available for just R170, while the 150w is R230. Let me know if you need any other details on these options! I'm still learning so my recommendations may not be perfect, but I'm trying my best to help find what you need at a great PriceCheck price.
