3W/5W/7W MR16 LED globe

A replacement LED globe on a two-pin low-voltage base, running on 24V. MR16 is a LOW VOLTAGE base and does not run on mains. It needs a transformer or driver behind it, and it is the base most often confused with the mains twist-lock type because the fittings look alike from below. If your fitting has a transformer or driver, it is MR16; if the cable goes straight to mains, it is not.

Globes are the one part of a light fitting that is genuinely consumable, and the reason to buy a good one is that a fitting outlives many of them. Getting the base right is the whole job – everything else is a preference.

Light output

It draws 3W, 5W and 7W and is rated at 400lm, 425lm and 450lm. The beam is 60.

It is a tri-colour globe: the colour temperature is selected on the globe itself – 3000K, 4000K and 5500K – rather than being fixed when it was made. That is genuinely useful in a replacement globe, because one part number covers a warm bedroom and a neutral kitchen.

Dimming

Havit does not list this globe as dimmable, so it should not be put on a dimmed circuit. On a lamped fitting the dimming behaviour follows the globe rather than the fitting, so a non-dimmable globe on a dimmer typically buzzes or flickers rather than dimming cleanly.

Getting a long life out of it

An LED globe rarely fails the way a halogen did. What kills it early is heat: the electronics sit in the base, and in a sealed or insulated fitting that heat has nowhere to go. A globe that dies within months in one fitting and lasts for years in another is almost always telling you about the fitting, not the globe.

If a fitting is fully enclosed, check it is rated for that before assuming the globe is at fault. The same applies to insulation packed against a downlight in a ceiling – it traps heat around the very part that is least tolerant of it.

Before you order

This is a LOW VOLTAGE globe. It cannot be connected to mains and needs the transformer or driver that is already behind the fitting. If you are unsure which you have, check whether the existing globe has pins that push in (low voltage) or a base that twists or screws (usually mains), and confirm the voltage marked on the old globe.

Take the old globe with you or photograph its markings. Our team at Lights For You can identify a base from a clear photograph, which is faster than measuring pin spacing.

Frequently asked questions

What base is it?

MR16 – a two-pin low-voltage base.

Does it need a transformer or driver?

Yes. It is a low-voltage globe and needs the transformer or driver behind the fitting.

Can it be dimmed?

No. Havit does not list this globe as dimmable.

How do I set the colour temperature?

It is selected on the globe itself, so decide before fitting it – especially if several are going into one room.

How do I check I am ordering the right one?

Photograph the markings on the old globe and send them to us – the base is the part that must match exactly.
