2026 Update: If you are replacing old halogen downlights, the main job is not picking a prettier fitting. It is checking the fitting type, the room, the dimmer, the colour temperature and the space you already have in the ceiling.
Key takeaways
- Start with the existing fitting, not the lamp wattage on the box.
- GU10 and integrated LED downlights solve different problems.
- Colour temperature matters more than most people think.
- If the light will be dimmed, check the dimmer and the product page before you buy.
- For bathrooms, kitchens and covered outdoor areas, check the room rating carefully.
If you want to browse the range first, start with our LED Down Lights & GU10 Downlights collection. It is the cleanest place to compare the main formats before you narrow the choice by room.
What changed from halogen
Halogen downlights are old technology. They run hotter, use more power and often force you to think about replacement costs as much as the light itself. LED downlights are usually the better long-term option, but only when the fitting and control gear suit the job.
That is why the question is not simply "LED or halogen?" It is "Which LED downlight fits the room, the holder and the way you want the space to feel?"
Need a starting point? Compare the main formats in our Recessed Lighting & Downlights collection, then check the product page for the exact fitting details.
What to check before you buy
1. Fitting type
If you already have a GU10 holder, you may only need to replace the lamp. If the downlight is integrated, you are usually replacing the full fitting. That difference matters for cost, ease of installation and future maintenance.
2. Colour temperature
Use the Kelvin value on the product page. In Future Light wording, 3000K is Warm White, 4000K is Cool White and 6000K is Daylight. For lounges and bedrooms, Warm White often feels more relaxed. For work areas, Cool White is a practical middle ground. Daylight is brighter and more clinical.
3. Dimming
Do not assume every LED downlight will dim properly. Check the product page, check the dimmer type and, if you are not sure, let an electrician verify the setup before you buy in bulk.
4. Beam angle and glare
Wide beam angles spread light more evenly. Narrow beams create tighter pools of light. Neither is "better" in the abstract. It depends on the room, ceiling height and whether you are lighting a task area or the whole room.
5. Room conditions
Bathrooms, kitchens, patios and other exposed spaces need the right rating. Do not guess on this one. Check the product page and match it to the space.
For a calmer home look, warm white is often the easier choice
If you want softer light in a bedroom or lounge, take a look at our Warm White LED Downlight 3000K 400 Lumens. It is a good example of the kind of downlight many homeowners want when they are moving away from older halogen lamps.
If you prefer a cooler, more task-friendly feel, compare it with a White LED Downlight Metal and Plastic 4000K. Comparing the product pages side by side is usually more useful than reading wattage in isolation.
GU10 vs integrated LED downlights
GU10 downlights are often simpler when you want to swap the lamp later. Integrated LED downlights are neat and compact, but the whole fitting is the thing you replace if it fails. Both have a place. The right choice depends on how you like to maintain the space and what is already in the ceiling.
If you are building or updating a room from scratch, our Dimmable LED Downlights | GU10 & Integrated Ceiling Lights collection is worth a look, especially where brightness control is part of the plan.
Room-by-room guidance
For kitchens, choose a fitting that gives you clear worktop light and do not place the downlights too far apart. If you need help with layout, our downlight spacing calculator is the better next step than guessing.
For bathrooms, check the rating first and only then worry about finish. For bedrooms and lounges, the colour temperature and dimmer compatibility usually make the bigger difference to day-to-day comfort.
For living areas where the ceiling is low, keep the fitting neat and avoid anything that throws light straight into your eyes when you sit down.
Common mistakes to avoid
- Buying by wattage alone.
- Ignoring the existing holder or cut-out.
- Mixing colour temperatures in the same open-plan space without a plan.
- Assuming dimming will work just because the box says LED.
- Choosing a bathroom or patio light without checking the room rating.
If the light is part of a larger refresh, it can also help to compare the room-specific collections. Try our Kitchen LED Downlights | Practical Ceiling Lighting or Bathroom LED Downlights | Safe & Practical Ceiling Lighting collections when the room needs a more specific answer.
Quick next step: If you are replacing more than one fitting, open the main collection first, then check one product page in detail before you buy the full set. That usually saves the most time.
Final thought
Halogen to LED is a sensible upgrade, but the wrong LED can still be the wrong choice. Start with the room, match the fitting, check the colour temperature and only then compare price.
If you want help choosing, browse the main downlight collections and work from there. That is the cleanest way to avoid buying the wrong fitting twice.
FAQ
Can I replace a halogen downlight with an LED downlight?
Often, yes. The safe answer is to check the existing fitting, the holder type and the product page before you buy. If wiring changes are needed, use an electrician.
What colour temperature should I choose for downlights?
Use 3000K Warm White for a softer home feel, 4000K Cool White for a cleaner everyday look, and 6000K Daylight where you want a brighter, more clinical effect.
Do I need a dimmable LED downlight?
Only if you want the light level to change. If you do, make sure the fitting and the dimmer are compatible. Do not assume LED means dimmable.
What is the difference between GU10 and integrated LED downlights?
GU10 downlights usually let you replace the lamp. Integrated LED downlights are built as a full fitting, so the whole unit is replaced if it fails.
Where should I start if I am unsure about spacing?
Start with the room layout, then use our downlight spacing calculator before you place an order.
