- Take CRI 90 where the beam lands on something - artwork, merchandise, food. Below that an accent beam flattens the thing it is aimed at and the piece looks worse lit than unlit.
- CRI 80 is enough for corridors and storage - save the higher rating for where it shows.
- Match it to the halogen it replaces - 6W for a 50W halogen.
- Check the dimmer on a full swap - a dimmer rated for a run of 50W halogens has a minimum load that a run of 6W LEDs may not reach. Flickering at low settings usually means the dimmer.
- Expect the head to stay cool - at 6W it can be adjusted by hand, which a 50W halogen could not.
- Twist gently into the socket - forcing a GU10 can damage the spring contacts.
Directional light with colour you can trust
MR16 is the reflector shape: a faceted cone behind the emitter that gathers the light into a beam rather than letting it spread. On a GU10 twist-and-lock base it is the standard lamp for track heads and adjustable downlights.
What separates this one is CRI 90. In a fixture whose job is to point at something — a painting, a shelf of stock, a display — how accurately it renders colour is the whole reason it is there.

Where CRI 90 is worth the difference
| Lighting | CRI needed |
|---|---|
| Artwork and framed pieces | 90 and above |
| Retail merchandise | 90 and above |
| Food preparation and display | 90 and above |
| Corridors and storage | 80 is enough |
| Garages and plant rooms | 80 is enough |
Below CRI 90 an accent beam flattens the thing it is aimed at. Reds go brown, greens go grey, and the piece looks worse lit than unlit — which defeats the purpose of pointing a light at it.
One eighth of the halogen draw
A 50W halogen in a track head runs hot and burns through its life quickly. At 6W the same beam costs an eighth of the power and the head stays cool enough to adjust by hand.
Check the dimmer on a full swap
A dimmer rated for a run of 50W halogens has a minimum load that a run of 6W LEDs may not reach. Flickering at low settings usually means the dimmer, not the lamps.
