3 or 5 watt led for bathroom?

Jimmy_Neutron

I had 4 "daylight" 3 watt LEDs put into my bathroom ceiling yesterday. The colour is very stark and clinical, plus they did not seem as bright as the 50 watt halogens they replaced. They are being replaced today with warm light bulbs - but should I ask for 5 watt bulbs, will they be a closer match to the halogens?

Why not compare the lumens output and the beam angle and see if they fit what you reuire better. Cool white or daylight will always give a clinical style light as is mentioned on virtually very single LED light posting on here

I would choose warm white bulbs, daylight or cool white give quite a bluish light. For equivalent brightness to 50W you need at least 5W, with 7W being a closer match.

The NEW genertion LEDs are rated at 370 Lumens and rated at 5w (though I think there actually 4.6 Watts). I have replaced all my 50w Halogens with these and if anything there brighter than the old halogen bulbs.

I wasnt convinced at first as Ive seen LED bulbs before that were not up to the job - but finally with the new gen ones they have got it right.

There not cheap though - I think I paid £10 per bulb when buiying 16.

These are the ones you want:

CANT EDIT FROM WORK !!!

When I say these are the ones you want - well there not lol. There the TYPE you want, but you need 12v versions for the bathroom, the ones I linked are 240v.

I havent seen any 12v ones personally, but have been told they are avilable.

Had a search. the 5w 12v ceilig lights seem fine. At 450 Lumens they should be fine:

I have just changed the GU10 low energy ones in both a bedroom and the kitchen with some SMD LED's They are 5watt and the blurb says they are equivalent to a 75 watt halogen. They are also warm light and are very good, one of the best things about them is that they are instant. Got them off eBay for £3.00 each.

Thanks for the replies. I checked the box that a bulb came in and it says 3 watt 235 lumens. So I should request the new bulbs to be 5 watt and at least 400 lumens?

paulmapp8306

I would definately. You need at least 370 Lumens to replicate a 50w Halogen.

I have recently replaced 35 out of 65 of my halogen bulbs with SMD GU10 bulbs. They are 5W and come in either cool white or warm white.

Firstly, like previous post, I am very impressed with the light output of these SMD bulbs with a 120 degree beam angle and easily compares to 50W halogen GU10 bulb.

I believe there is a two year warranty on the bulbs as well and have a claim of 40,000 hrs.

Too early to say if they will last but overall I am impressed with the output and will be placing another order for the remaining bulbs.

If you want details of where I got the bulbs from PM me and I will send you details. They are dearer than the ones of eBAY but I did find the company at the Home Show at Olympia last month, hence confidence factors into it for me.

I was pondering swapping my 300 watts worth of kitchen lighting for some of these, if 5 watts of LED equals 50 Watts of halogen. That works out at a saving of 270 watts per hour so to save 1 KWh worth of electric will take 3.7 hours. The cost of the bulbs is £80 for 10 so as I only need 6 that's really only £48. On my tariff electric cost about 12p per KWh so £80 will buy 80 / 0.12 = 667 KWh of electric. To start saving any money will take 667 x 3.7 hours 2470 ish hours.

Is it actually worth scrapping the old bulbs or wait until the bulbs pop and hopefully the LEDs get a bit less expensive. They have been in for a few years so probably had half their life

Ok I spoted the error 48 / 0.12 is 400 so it's only 1500 ish hours, still a lot of hours
