They appear to have changed the design, I can not get any bulbs to fit.** A: g24q-1, g24q-2, and g24q-3 alignment ridges are all in different configurations (centre, left, right). g24q-1 are the centre aligned fittings. **Q: Do the bulbs fit into standard lamp shades {ceiling}** A: The end of these globes/bulbs are rectangular with 2 pins and are generally for bulk head and fixed position lighting and "push" into position. I don't know of any standard lights/hanginglights with this type of bulb. The lights I have with these bulbs are fixed downlights with 2 of these per downlight. Hope this helps. **Q: This is advertised as 4 pin, yet several reviews refer to its being 2 pin. Exactly how many pins does it have? My socket has 4 holes!** A: You have to make sure you order the 4 pin, 2 on each side, if it is advertised as 4 pin then that is what you get and they are a hell of a lot cheaper on here than in the shops, e.g. nearly £8 each, ripoff.. **Q: Is this bulb the same as the crompton clde 10scw? i grudge paying a fortune for a bulb!** A: No this is NOT the same bulb. You must replace these lamp with a like for like wattage . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by A***S on 23 September 2026* Good purchase ### ⭐⭐⭐⭐⭐ Great *by T***D on 30 October 2025* Working perfectly… ### ⭐⭐⭐⭐ Bright and durable *by S***N on 18 April 2022* The shape of the bulb was 99% the same as my socket with a small difference which I didn't realise in the pictures. This shape is very difficult to find instore and I have tried a number of them. Initially, I thought to return it however I just used the cutter to cut a small plastic piece and there you go it fits in perfectly now. All is good now and it's bright and working just fine. ## Frequently Bought Together - OSRAM DE13W840 13-watt Osram Dulux 4000K 4 Pin Base Fluorescent Lamp - OSRAM FCS 64640 HLX 150W 24V Tungsten Halogen Lamp - OSRAM FCS 64640 150W 24V HLX Halogen Light Bulb --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/48611947-osram-dulux-d-e-13-watt-cool-white-4000k-compact](https://www.desertcart.at/products/48611947-osram-dulux-d-e-13-watt-cool-white-4000k-compact) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-17*
