Can I use GU10 LED bulbs for light?

[wahaj]

Hiya,

I'm trying to find a cost effective and eay to find system to provide suplimentary light to my orchids, especially over winter.

I've been told LED bulbs are low cost to buy, run and find.

I've found GU10 blue LED bulbs in a local DIY store (B&Q) and am wondering if I can use those. If I use a mixture of red and blue bulbs, would that be right?

Or should I be using the white light GU10 LED bulbs that they have?

Can these particular types be used as grow lights or do I need to get something that specifically states they can be used for hydroponics?

The ones I saw are like these ones:

Thanks!
