We bought one of those little desk lamps with the telescopic arms that allowed you to adjust it up and down. Daughter placed it (at full extension) over her small tropical fish tank to illuminate it though the clear lid.

After a few days use she noted that the plastic base (with the transformer) had badly melted (nothing to do with the light) so we took it back.

We told them what it was used for, stating that it was typically on for a good few hours and they tried to suggest that 'wasn't what it was designed for'?

I tried some logic ... 'No mention of it's duty cycle in the manual. It's a desk light that was being used to produce light on a desk' and even said that we would be happy to pay more for something that wasn't likely to melt. No solution offered, 'our fault'.

I asked for their name and they asked why ... 'So I can tell Trading Standards who I was speaking to when I speak to them ...'.

They offered us a full refund and we chose something less likely to burn the house down (that worked fine). ;-)

Won't the LED be far more efficient?

This suggests:

Whereas for the 35W CDM-T it will be 79l/W

I was pissed off with the halogen bulbs in my kitchen blowing after about 6 weeks. They were 40w, I swapped them for 14w PAR38 LEDs. The amount of light in my kitchen is brilliant. I would guess somewhere just over 500 lux. I just had a dig through my email, they have been up since October 2016, none have been replaced. Brighter, cheaper to run and last. Only downside is I did not look at the dimensions and had to get adaptors for them to screw into the holders. They are one of the best buys I have ever made.

Did you try buying quality ones? ;-)
