Hi Just joined the forum and very impressed with the help provided in the health forum and with the research article. Yesterday I was browsing a UK tortoise shop website and thinking most of the lamps look like the cheap desk / spot lamps available in many supermarket or electrical outlets and the bulbs seem to be halogen spotlight bulbs with very little info provided about bulb output. Your article would be very useful for such outlets to read but I imagine many would not take much notice. I will Tweet a link to it later today.

According to a Radio 4 item yesterday, domestic halogen bulbs are due to be phased out in favour of LED bulbs, either as early as 2016, or possibly delayed until 2018. (See: http://conversation.which.co.uk/energy- ... gy-saving/ ) IKEA are leading the way ahead of the withdrawal of halogen bulbs by already selling only LED bulbs. These are considered to be very efficient in that they give off virtually no heat.

Meanwhile I'm still using incandescent bulbs: reptile keepers need bulbs that provide both light and heat.

At the moment, fortunately some tungsten spotbulbs are still available. Used in combination with fluorescent UV tubes, I rely on these: http://www.homebase.co.uk/en/homebaseuk ... ack-788278 (althoug hI use the 120W versions). I'm dreading the day when they are withdrawn.

The PAR 38 floods are being replaced with these (or something similar):

https://www.diolighting.co.uk/LedBulbs/ ... itting=E27

Nice enough light... no heat.

There will probably be a 'dodgy' market in 'illegal' lamps.... pssst! Got any 120w PAR 38's, mate?

Meantime, all the more reason to get building some nice solar powered units!

If there are already alternatives, then clearly the days of the PAR 38s are indeed numbered. Time to start stock-piling then!

:lol: Yes...if I buy enough now, I could be that dodgy dealer!

True, but today it's raining, and soon, apparently, it will be winter... :(

Hi, regarding basking spot temps, how do you measure these areas using an IR thermometer please?

Seems to be a lot of info about ideal temps, but much confusion on how to correctly measure them.

I've had people tell me you should check the substrate temp under the lamp, but I find this varies greatly on the medium used and how damp it is at the time etc. What I have mainly been doing is to check the shell temp of the tort while basking and changing the hight of the lamp (Arcadia 100w MVB) if the temps are too high or too low. Aiming for a shell reading of around 32-33.

Hi Andy,
Just been reading part two the Lumisol has me interested, but could you tell me the disadvantages of say if i used clear acrylic sheet instead of Lumisol the acrylic still lets UV through and is a bit stronger the film ( I have two cats that will want to walk over the film. Yes i know the acrylic will yellow and degrade within two/three years but is it usable?

The film is actually better in many ways than the acrylic... it is thinner, for one thing, and that equates to less absorption.

Cats? Not a problem. Put the film behind a protective 'cage' made from twin-weld. That does block a small amount of light and UVB but it is not really significant outside.

Thanks for the reply Andy,Now a word of warning about buying Lumisol,yesterday and today i have rung quite a few suppliers and none of them will sell less than 7.2m x10m at a time at around £105 to £130 including shipping. i did find one in Devon who took my order for 7.2m x 1m and the money £21odd, this morning i recieved an email from them saying they would not supply unless i upped the order to 20m so i said return my money!! several other dealers have different types of Lumisol and they say they are just as good so im not sure they know the tec side of things It would appear the best way to buy is for a group buy,anyone in essex or close interested in this stuff i dont mind doing the ordering, example 10m was £115.80 but 15m was £101.55!! crazy.actually my requirements are can be got out of a strip 7.2m x 1m!

Just found out that Northern polytunnel will sell 7.3m x 5m Lumisol clear for around £50.
