Walk through any Norwegian home in the evening, and you will see the same thing: cold, white LED light pouring from the ceiling. Kitchens, living rooms, even bedrooms. The colour might look "normal" to the eye, but your biology does not agree. That is the key here, your biology doesn't understand that light as it is in a completely "alien" ratio.

Your bright white lights are packed with blue wavelengths, sometimes green too, and they do not belong in your home at night. Well, at least not in the spectrum ratios they are being pumped out in. They keep your brain awake, suppress melatonin, and disrupt circadian rhythm. If you have wondered why you lie awake even though you feel tired, your light environment is a big part of the reason.

Why I Don’t Sell Incandescents (and I Wish I Could)

Incandescent bulbs are one of the healthiest sources of indoor light. They produce a warm spectrum, more like firelight, with very little blue. Used in the right way, they can be therapeutic (because of the large portion of infrared that is emitted). The problem is that the EU banned them. Not because of health, but because of energy efficiency. Rules written without any understanding of biology. I want to moan about this, but all I can do is hope that people see sense and bring back incandescent bulbs as they are so much healthier than standard cold LED lights.

Again, I would stock them if I could. Unless you find old stock somewhere, they are no longer available to import here. It is frustrating, because what looks like progress on paper is actually a setback for human health. If you can, I would encourage anyone reading this to seek old stock (they are still available in Norway and you can even find some versions in shops, but you need to look).

What I Offer Instead, the Next Best Thing

Since incandescents are restricted, I have brought in alternatives that remove many of the downsides of normal cold (and even warm LEDs).

• Amber bulb: No blue light, only warm amber. Perfect for evening use in living rooms and bedrooms. It feels calm, and it does not signal daytime to your brain. It reflects early sunset in my opinion. 
• Red bulb: No blue and no green. This is the closest you will get to firelight. Use it in the last hours before bed to help your body prepare for deep sleep.

Both options are available in E27 fittings (and from next week you will be able to purchase E14 bulbs in two designs in amber). So you can simply screw them into your existing lamps. No rewiring. No special equipment. Just a healthier spectrum of light where you need it most.

The Deeper Impact of Wrong Light

When you sit under bright, cool LEDs after sunset, it does more than lower melatonin. Specific blues and into cyan wavelengths tell your mitochondria that it is daytime, which can raise evening cortisol. Elevated cortisol keeps your body in alert mode instead of recovery mode and can also effect protective gene expression..

• Cortisol up at night means poorer sleep and a harder wake the next morning.
• Hormonal changes driven by blue light can lead to blood sugar changes. Think about - could this explain why many people crave snacks late in the evening. Your biology thinks it is still daytime and looks for quick energy If you combine that with quick dopamine hits of phone and tv use, then your body looks for dopamine hits in other places....... one of those is food.
• At the mitochondrial level, excess blue light increases oxidative stress. That means less efficient ATP production and more free radicals. Sleep is when your body clears these byproducts. If sleep is already compromised, the cleanup never finishes.

From a quantum biological perspective, photons interact directly with multiple light receptors including mitochondrial chromophores and cellular water structures. The wrong wavelengths shift redox balance, alter electron flow, and change cellular signaling. Those shifts show up as inflammation, cravings, energy swings, and cognitive fog over time. This is not only about feeling sleepy or awake. It is about how your cells produce energy and recover each night. You might be thinking - well at least the LEDs you have at home are good for day time?? The reality is they aren't great for that either. You see, the blue wavelength for peak alertness is around 480nm. In modern lightbulbs, the peak blue is around 440-460nm and then there is a steep drop off into 480nm. So you are getting blue, but not the best for daytime productivity. Many end up with too much broad spectrum blue from 440-495nm at night and not enough 480nm during the day.

Why Environment Matters More Than Glasses

I also sell blue light blocking glasses (Here), and they help when you cannot control the light around you. But the real win is fixing your environment first. Glasses are a useful tool and brilliant if you want to continue using screens. However, changing the bulbs in your home is a behaviour change that supports your biology every night without thinking about it.

If your living room is bathed in cold LED light, your brain is getting the wrong message. Swap the bulb, and your whole household benefits. Kids, guests, everyone in the room. For you and your family, I would recommend both, but with guests, perhaps having the room lighting works best.

Guests that come to my house after sundown are always amazed how relaxed they feel in the amber and red lighting. It is a running joke with them all that my house looks like a brothel from the outside because of the red light, but each and every one of them have since purchased lights as they love how calm and relaxed they felt.

The Colour of Your Nights

Ask yourself: what colour is your home after sunset? White? Blue-white? Or warm amber and red? Your answer matters.

• White light at night equals confusion for the circadian system.
• Amber light equals a calm transition to evening.
• Red light equals a clear signal for sleep.

This sounds simple, but it is the foundation of hormonal health, energy, and mood regulation and it can be that simple. Of course, as I mentioned above, if you are on your phone or the TV has the backlight up to the maximum, then you will need blue blocking glasses. However, you are already adding more warmer, longer wavelengths tones into your environment with the LEDs. If you find some incandescent bulbs, you will add even longer, healing tones into your environment.

A Norwegian Reality That We Need to Confront

We spend a large part of the year in darkness (some people up north, in complete darkness without artificial light). That means artificial lighting is not decoration, it is a necessity. It is biology, your biology, and it shapes everything that goes on inside you. It shapes how you sleep, how you wake, and how resilient you feel through the long winter. How your mood is, how your form is, and how you progress through to awakening spring next year! We are deprived of the light that we need to thrive, it's OK to admit that. Once we admit that, we can do things to improve our light environment and make an effort to incorporate other things which can help when the light "has gone" or is diminished - like cold and light therapy panels.

The EU has taken away incandescent bulbs (stupidly in my opinion), so we adapt. My goal is to make sure you can do that without sacrificing health here in Norway. Amber and red bulbs are small changes, but they make a clear difference when used nightly.

Buying from Home Light Therapy should be something that you have absolute confidence in. I have tested them myself, measured the spectrum with my own equipment, they have been independently sourced and verified by independent companies to make sure they meet the manufacturing and safety standards. I wouldn't sell anything I don't use myself, and I use them in my home. I will soon be stocking such much better Daylight LEDs so keep a look at for those! Again, these aren't perfect, but they are better than the normal.

Light is life. In Norway, the right light improves quality of life by improving your biology.
