LED Bulbs. Help!

Mr_Toad

I have bought a box of 10 cheap GU5 from eBay for £12 inc P&P from a UK seller for my boat.

I have 30+ of the 12v halogen GU5s on there and decided I'd give LEDs a try and at £12 for 10 it seemed worth a go.

I fitted them in the main saloon cabin and they are excellent. Obviously I can't comment on longevity since they only went in just before Xmas but with all the saloon lights on the drain on the batteries is substantially less than it was with the halogen bulbs.

I shall be replacing the rest over the next few months.

So, using the same logic, i'm steering people to a competitor as well even though i've not named either company? As i say, i've never named my company on this forum and i won't, but i will name a competitor as their products are absolutely superb. They are http://www.soraa.com

My sole interest is to provide people with the right information so that they can see through the many traps and lies, make informed buying decisions and end up with LED's that will perform as advertised - as a large majority do not.

I did make it clear that I believe you are not touting for business here and are only trying to help others with your posts. I just feel transparency costs nothing, adds to your credibility as someone who knows their stuff, but also reassures people that you are beig upfront about your own interest in the industry. Sorry if it didn't come across in the way I intended.

It is factually correct to me if I perceive it as brighter. That is what counts (to me) and that's what I wanted to say. Maybe the term "brighter" is used differently in a technical context, I and most people don't care.

No tronator. If you prefer 3000K to 2700K because it is 'more white' or 'less yellow' that's fine. That IS colour temperature. The measurement of brightness is Lumens. Not measured by your eyes.
As everyone in this thread knows, elstimpo is in the industry and knows a lot more on the subject than you and has patiently and politely tried to correct you, but you're stating your opinion as if it is fact.

You too didn't get my point. What matters to ME is what I perceive. I'm sure you both are technically correct.

It's similar to when ad breaks on TV seem to be louder than the rest of the program. Technically they're not louder but will be perceived louder due to the compressed audio. So next time my GF askes me to turn down the volume I'll tell her that the ad is not louder, only more compressed?

One thing I will say, and that is, as a keen photographer SMD bulbs with a 2700Kelvin output are ideal for use as hot-lights.
They work in the same light spectrum as sunlight through a standard glazed window and give the best white balance.

They also run very cool in comparison to proper studio bulbs, which means they are well suited to use with improvised barn-doors and home-made filters.

Anyway, the 2 SMDs I ordered last week have arrived. I went for a 10w globe bulb and a 12w corn bulb.
The globe bulb despite being lower wattage, is actually brighter.
If I order any more, I will be going for a higher wattage globe rather than the corn bulb.

Slightly OT? Maybe not??

The good lady has just purchased a pair of these
http://www.diy.com/departments/colours-komet-pendant-ceiling-light/177145_BQ.prd

They require 20 x E14 lamps (my son in law is an electrician, so I know not to call them bulbs! ) in each one.

While we are blowing the budget we may as well get dimmable LED's and they should be the 'golf ball' type

Can you knowledgeable folks advise a 'best buy'?

I do understand - just make sure you don't get your perception mixed up with being technically correct - your original statement

I bought 8 of those 2 years ago and they're brighter than the 50W we used before.

didn't include 'perception'.

There seems to be a belief that whiter is better, even getting into blue - it's not. You've lived your life under 2700K - the sun, and most of the 'nice' lights - traditional Edison bulbs, halogen etc, are the same colour as that, whereas poor fluorescents are often called too blue, green or white. So don't fall into that same trap with LED.

How bright do they need to be? Since they are so many I guess they don't need 50W of the old type. Maybe these will do?

I don't use them, just did a search on Amazon. Since it's free delivery, you might want to order one 10 pack before ordering the rest.
