      Beam Angle

      The beam angle is how wide the beam is spread. If you have a very narrow beam angle your light will be projected like a handheld torch whereas if you have a wide beam angle it will be much softer and spread like a traditional bulb. Wide beam angle are best for living areas such as living rooms, dining rooms and bedrooms where you are looking for a softer light and narrow beam angles for targeting specific areas or for decoration.

      320 Lumens

      Since LED light bulbs are designed to use less energy than halogen spots, wattage is not a reliable way to gauge how bright the bulb is. Brightness is measured in Lumens.

      With LED spotlights there is more to consider than just a direct Lumen comparison with the halogen equivalent. The superior light quality given off by LEDs and much lower bulb degradation rate over time must also be taken into account. This is why the stated Lumen output for an LED spotlight is often less than that quoted for a halogen spot bulb it replaces.

Wide beam angle are best for living areas such as living rooms, dining rooms and bedrooms where you are looking for a softer light and narrow beam angles for targeting specific areas or for decoration.

      120º

      Size (mm) (50 x 50)

      The size determines the diameter and the length of the bulb. In most cases the bulbs are a retro-fit, which means they are a direct replacement for their halogen equivalent.

      Input Power

      This is a measurement of the volts required to operate the bulb. The standard for the UK is 240 volts. This means that you can plug these directly into existing fittings without changing any of the electrics.

      Replacement For

      This details what this LED bulb is a replacement for in terms of standard halogen bulb wattage. This allows you to easily make a comparison when replacing your existing halogen bulb, to ensure you get a similar light quality and brightness from your new LED bulb

      Voltage

      This is a measurement of the volts required to operate the bulb. The standard for the UK is 240 volts. This means that you can plug these directly into existing fittings without changing any of the electrics.

      Average Life in Hrs

      Manufacturers will give lifetime claims in multiples of 1000 hours. One thousand hours is equivalent to about 6-months use when the bulb is on for 4 hours per day. A traditional halogen spotlight bulb is expected to last about one year (2000 hours) where as an LED will last between 30,000 and 50,000 hours - that’s between 15 and 25 years! Switching to LEDs means you may never have to change your light bulbs again.

      Dimmable (Option)

      Dimmable LED bulbs are only compatible with a dedicated "Trailing Edge" dimmer switch that reduces the current flow. Your bulbs will not work effectively if used with the conventional "Leading Edge" dimmer switches that operate with a higher current flow.

      When ordering dimmable LEDs please ensure you have an LED-compatible Dimmer Switch.

      Base

      This is the fitting of the bulb, described by a letter/number code. You can find out what your fitting is by looking on the base of the bulb you are replacing or the packaging of your existing bulb.

      Wattage

      The wattage is the value given to the amount of power consumed by the light bulb itself. So, a 50-watt halogen spotlight bulb will use 50 watts of power. If you have 6 x 50-watt halogen spots in your kitchen then you will be using 300 watts of power. If you were using replacement LED lights at 4 watts each you would be using 24 watts of power, resulting in huge energy savings.

      Warm, Daylight, Cool

      Warm White is similar to conventional lighting and has a softer feel.
      » Perfect for areas such as living rooms and bedrooms.
      Daylight colour is used to represent 'daylight' indoors. It has neither the softness of Warm White or the starkness of Cool White.
      » Suitable for lighting all areas.
      Cool White is a brighter, whiter light.
      » More suited for the Bathroom and Kitchen.

      Power Consumption

      The wattage is the value given to the energy consumed by the light bulb itself. So, a 50-watt halogen spotlight bulb will use 50 watts of power. If you have 6 x 50-watt halogen spots in your kitchen then you will be using 300 watts of power. If you were using replacement LED lights at 4 watts each you would be using 24 watts of power, resulting in huge energy savings.

      Protection Rating

      The IP rating is an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, fingers) and moisture. IP65 for example, is dust tight and water resistant.

      LED Chips (p/m)

      There are 2 options to think about when choosing strip light. The size of the LED chips and the amount of chips per metre. Our LED Strip comes in 60 LED's per metre or 120 LED's per metre. This indicates how many LED's are attached to the strip which powers the LED's. The chip size comes in 2 types, large (5050) and small (3528). The bigger the chip, the more light it gives out.

      Material

      This is to describe what material the product has been crafted with e.g. Aluminium

      Chip Model

      The chip used within the device is typically manufactured for a purpose e.g. torch, bulb etc. Here we describe the manufacturer of the chip and any special characteristics.

      Colour

      This is the colour of the casing.

      Modes

      Modern torches and battery powered lights now come with various modes as standard. Typical modes are a minimum to maximum light output staged over two/three modes. A strobing mode and and SOS mode are also quite common.

      Beam Distance

      This is a measurement of how far away the beam of the torch will usefully light an object.

      Reflector

      The reflector is the most important part of a torch.  It gathers the light from the LED Chip and focuses it into a beam.  

      There are two main types of reflector surface - they can be "mirror-like" or textured "orange peel". The orange peel type give a smoother change from the hotspot - the brightest part of the beam.  It also evens out slight imperfections in production.  Orange peel is by far the most popular kind of reflector.

      Waterproof Rating

      e.g. an IPX7 rating for a consumer device specifies that the device has water protection up to limited immersion, typically up to 1 metre. IPX8 indicates the device is protected to a depth of more than 1m metre. Please read product description for full details.

      Lights swapped with existing halogens no problems, slight flicker occasionally so might need driver. Used in kitchen so went for cool light-Ok for kitchen but is definitely a bluer colour than existing-makes unit lights look very yellow, so maybe warm light would be better next time. Definitely bright enough though.

      5/5

      I installed 4 new 12v halogen bulbs at 35watts each, having LED's in other rooms I knew that there was alternatives, so I bought these, though this is the first ones on a 12v circuit. The luminence isn't quite as much as I got used to the 35w halogens, but the colour is day light which isn't far off the room in actual day light, though a positive note is that as the halogens were quite "spot" on the surface, these are nicer spreading the light out from the same point. Anybody installing on an existing circuit, though i'd recommend the transformer as it's built to supply LED's.

      Does exactly what you would expect of an LED bulb. I recently moved and found the previous occupants had 42 Halogen bulbs on the ground floor alone. The electricity meter was having a fine time spinning away. I replaced all the bulbs from LEDHUT and the meter is now barely moving. Well worth it.

      These lamps were to replace 50W halogen versions, and they were really not bright enough as direct replacements. Also, I notice some flickering of the LEDs, which is a nuisance. On the positive side, they do what they say in terms of energy saving, and my array of 8 ceiling lights has fallen from 460W to 35W!

      I have these in my kitchen and they are great replacements for my halogens. The biggest problem is interference to my DAB radio, quite bad and problem really does need to be solved.

      Used in our bathroom to replace halogen lights that kept blowing. Much improvement in light and should last for ages and cost next to nothing to run. Recommend to anyone. Product quality seemed OK visually and gives off a great light better than the 25 watt halogens fitted before.

      Bought it for my bathroom in cool white. Much better than the 150W halogen bulbs I had in before. Hopefully it will start giving me savings in a few months. Good brightness. I reccommend it. better than the warm white ones

      The warm white is my favourite tint, it feels more homely than the more actinic bluer whites. The bulb is a perfect size to replace halagen bulbs and lasts 15 times longer (so far, there still appears to be plenty of life in them!) and pays for itself within a year. At 320 lumens it gives out good light, easily matching the 50W halogen it has replaced.

      bulbs very good, pity they don't seem to be still available and I am getting really fed up with being asked more questions/sent more emails all the time

      4/5

      Used as replacement for 50W halogen. Would have liked it to be a bit brighter but could not find an alternative anywhere anyway. Wide beam angle works well except for bath/shower room where bulb sits in a bit deeper in casing.

      Seems good quality, direct replacements for standard MR16. Been installed for a week with no problems lets hope they last the 5 years!
