    A new light fitting uses five G9 halogen capsule bulbs. Anyone recommend a good brand of LED replacements?

    Am looking for 300lm+, warm white, sensible lifetime, <£2 each, not too bothered about CRI or dimming.

    Thanks!

    When I bought my GU10s, I bought one of every brand I could find and compared them. Crompton seemed to be the best so I bought 50. None have failed so far, after five years and we've been very happy with the light quality. So I'd recommend you at least include Crompton lamps in your trial :bigsmile:

    Looking at https://www.cromptonlamps.com/Catalogue/LED/Capsule/G9/LED-G9-Capsule-25W-2700K-3415 though, you're going to be whistling for your 300 lm though the presumably more expensive https://www.cromptonlamps.com/Catalogue/LED/Capsule/G9/LED-G9-Capsule-Sunset-Dim-Dimmable-3W-2800K-G9-9974 seems to meet it. No idea about price of either. edit: though a very quick google shows you'll have to dig deeper in your pocket.

    Previously bought ten lamps for £8.99 from eBay but that vendor has since disappeared.

    Has anyone tried this brand? https://amazon.co.uk/gp/aw/d/B07KWWXFBQ
