Lighting

[Arthur Marshall]

Up to now I've always used fluorescent tube lighting in the tub - each unit has two 8 watt tubes.  As one cabin unit has just died and the other probably will soon, it's time to replace, and I was thinking LED.  Any recommendations that would use less power for the same light? I've only got one domestic battery so power saving is fairly crucial.

You can get 12v LED tubes which are a direct replacement for those fluorescent tubes. You just by pass the units inverter.  Check them out on Bedazzled website.

Could you modify the existing housing to accomodate LED's

He’d have to, to follow Biz’s advice.

Sounds reasonable to me. But what do I know?

The bumpf says that one T5 tube is equivalent to 3 fluorescents. Does anyone know if that's borne out in practice?

[Billy Boy]

If they are labcraft lights they now do led equivalents. I got mine from there agent Dun-Bri. They may have a Dun-Bri near you if not phone labcraft and ask who stocks them closest to you. Hope it helps.

I would say from experience of my led spotlights that that seems a very reasonable assertion, may even be an under estimate.

Nice little comparison chart in this article

https://www.thesimpledollar.com/the-light-bulb-showdown-leds-vs-cfls-vs-incandescent-bulbs-whats-the-best-deal-now-and-in-the-future/

ETA having read the article through it would seem that in terms of wattage then it's about 6:1 for incandescent to led and less for CFL which they show as 1.4:1. I suppose it all depends on what is meant by "equivalent to 3 fluorescents"

Yes, but you need to be quicker then! It's no use typing interesting questions if you are not quick enough. We were all discussing what WotEver knows by the time you got round to replying.

We had two lighting units in the kitchen of our boat, both of which consisted of two 12v fluorescents. I have put 1 odd Bedazzled LED tubes in each lighting unit. A single LED is much brighter than the 2 fluorescents.

Hope that helps.

Yes we replaced ours with Bedazzled ones. One LED tube is as bright as 2 fluorescent tubes, which is ideal in the lounge and kitchen but actually makes them too bright in the bedroom (where there are two fittings that used to have one tube each) and I wonder if there would be a market for a half-power version as well.

They have these lower wattage tubes at Midland chandlers. You may not expect this but they are cheaper than Bedazzled. However the tubes I bought from Bedazzled are excellent.

[Arthur Marshall]

Fitted the bedazzled tubes this morning. Certainly seem a lot brighter than the old ones - shall be trying them out properly over the weekend.  Thanks for all the advice as ever.

If  I may be so bold What's the wattage difference between the CFL and the led?

No need found the info now thanks
