You don't need to buy Hue... Their 8W 800lm bulbs are €4 a piece in Europe, and a lot less in bulk. So 4x more expensive at worst.

Philips' discount brand (Attralux) is even cheaper, I recently bought more of these 8W 800lm for less than €1 a piece. For now I cannot tell the difference.

True, however they are worth the price. I used various brands of LED bulbs for a long time (such as Cree), basically whatever Home Depot was selling. The failure rate was extremely high. In 2017 I switched to Philips LED bulbs, and just last night the first one failed. Overall they are worth the extra up front cost, they'll save you money in the long run.

I have three weighty Philips bulbs mentioned in the teardown as carriage lights on the exterior of my house. They've been on 24/7 for maybe seven years now.
