Product Description

At 45w this is a low energy helix spiral CFL (compact fluorescent) lamp that produces a lot of light. Think small-sun amounts of light. OK so maybe that's exaggerating a little, but this lamp is the brightest low energy lamp we have ever seen. It blows everything else out of the water. With the consumption of 45 watts of power this lamp produces 3000 lumens, which is roughly the same as a 225w incandescent light. This light has a BC (Bayonet cap, B22) lamp base. This crisp white light is a good choice for any area where work is done e.g. Kitchens, Bathrooms, Offices, Studios. Also suitable to help with Seasonal Affective Disorder (SAD). These high output Green Lamp bulbs (45w - 105w) can sometimes emit a slight buzzing noise when they are in use. If you are using them as hi-bay replacement bulbs or will be some distance away from them when they're in use, then you are unlikely to notice anything but these bulbs might not be ideal for use in an otherwise silent room. The manufacturer have said that the buzzing noise does not in any way effect the lifespan or light output of the bulbs and is normal, but we at My Green Lighting wish to make you aware of the issue before you purchase as we cannot replace any bulbs which exhibit this behaviour.

The item arrived promptly and was very well packaged.

Do be aware that the bulb is absolutely enormous though. If you look carefully at the photo and keep reminding yourself that the bayonet connector is a full size one then you might get some idea but even that doesn't prepare you for the shock when you see it.

Edit: Also it makes a quite pronounced humming noise when it is switched on.

I use one of these bulbs in my garden shed (7x6ft) and it gives a very good 'daylight' approximation too the light given off. Much better than an ordinary 60 watt equivalent low energy bulb, which is much more yellow in it's effect. If you are looking for a 'white' light bulb for a small room/shed, then look no further.

I have also put 4 of these in my garage (10x35ft) and they now light the place up much better than the 3 old 6FT strip lighting and the 3 occasionally plugged-in 'hand-held' 60watt bulbs that were being used. I could have got away with only 3 of the new bulbs, but after having the wiring put in for the extra bulb, I didn't see the point in NOT using the 4th bulb.

Although it is too early to comment on their longevity in actual use, I highly recommend these bulbs if you need a 'white' light. I now have my eye on the bigger versions - 65watts and 105watts.

This is a big one. It measures 210mm long by 80mm diameter. Make sure it will fit both in terms of length and also that the diameter is not too large for your light fitting/shade.

It arrives beautifully packed in moulded polystyrene in a box and in a bubble wrap package.

It is a very white, very bright bulb. Seems instant or perhaps I simply cannot tell the difference between super bright and incredibly bright. In a small or medium size room it really is like daylight. I am left wondering how bright the 65 or 85 watt versions must be. This is enough for my rooms.

This light bulb arrived promptly and very well protected by polystyrene box. It's actually larger than I thought and gives off a strong bluish white light. I think it will keep my indoor plants growing strongly during the winter when light levels in the far north are low.

I bought one of these in December 2011 and have been using it for around 12 hours a day since then and it is still working fine. I use it as an additional light source for various seedlings . I can't really tell how much difference using the lamp makes compared to only natural light from the window, but I think the light helps seedlings to grow and I doubt they'd grow as well relying only on natural light, especially when the weather isn't sunny. I'm really satisfied with how long the bulb has lasted and think it was really good value for money.

I hate getting up in the dark, and always found that I wake better if I can get into sunlight, as in the summer. Not much chance this far north for half the year. This light seems to help, I have had a chance to try it for a few cloudy mornings so far, swithching it on when I want to get up. It is really white and bright. As my wife said, with her eyes shut and buried in the pillow she can still tell when it is on. It is mobile, so it also makes a brilliant worklight in a dark garage. It makes the warm white lights look dull and miserable. It is about three times as BIG in all directions as the normal 20 or 30W bulbs, so should be cooler and last longer. Read the dimensions and check the size of your lampshade. The green heatshield and ventilation slots should also help to keep the electrics cool. It does have a slight buzz, but I immediately stopped noticing it, it at was no bother at 2 foot, and I can't hear it over the kettle.
