energy friendly bulbs

[EdT]

Recently got 4 energy happy GU10 bulbs with fluorescent innards four our kitchen. They're a nice white 2700K so easier on the eye then LEDs, but take an age to get going & when at full pelt still not as bright as the original bulbs. Is there anything else to try?

Go for a higher watt equivalent, with energy savers.. i.e. replace a 60W with a 100W equivalent.. Some do start up a little quicker these days, Philips I think.

Can you tell me what you use. We have 12 GU10s in the kitchen and another 6 in our garden room. The bulbs blow so fast and are so expensive I thought I would try low energy long life ones

seems like sound advice

These work really well:

As has been said try a higher wattage but also try a different colour temperature 2700K is also known as very warm white, you may be better off with 4000k (cool white)which is a crisper white light may be better in a kitchen.

Some companies also make 6500k which is known as daylight.

The variation in warm-up times between the different brands of lamp is down to the ammount of mercury in the lamp. Some manufacturers opt to be more environmentally friendly and use minimal mercury which results in a longer warm up time. Others use a little more mercury to achieve a faster warm-up time.

The GU10 CFL lamps are generally slower to strike and warm up than a larger low energy lamp because the tube diameter is smaller and the bends in it are quite tight.

I dont think there is much between any of them in GU10 guise but make sure you go for at least 11W.

For GU10 I would go for Megaman 11W or Crompton 11W. I think Megaman offer a higher wattage but even their own tech guys say its not worth it as the light output is not visibly improved.

The total light output on a GU10 CFL is limited by the fact all of it has to come out through a small opening at the front - if you increase the wattage, the effect is minimal because the losses within the lamp are quite high.

The initial set I bought were all 9 watt, I then got a single 13 watt to compare & really cant see very much difference.
Have just seen that warm white LEDs is available - would this be a better option?
