Sigma HS3 Halogen (10-pack Blister)

If you still use halogen bulbs then these are highly recommended. Probably the cheapest around for a pack of ten and top quality. Just over £1 per bulb. Many people charge half of the cost of this pack of ten just for one bulb. I have used these more than a dozen times so far with two pairs of Lithium ion batteries in series. Each battery charged to 4.2V so two in series giving a newly charged voltage of 8.4V although this does reduce quickly to about 7.6V. The bulbs seem very tolerant of this higher voltage and are a little brighter as a result. If I find in the longer term that the higher voltage becomes a problem then I shall resort to using LiFePO4 batteries which have a lower voltage of around 6.4V for two in series and so closer to the bulb's specification. However, so far these have been absolutely brilliant, just as a bulb should be!.

Attention, il s'agit bienune ampoule, et pas 10 lampes halogenes. Donc le libellée de "set de 10 lampes halogenes est faux"!!!

Ottimo rapporto qualità prezzo.Le ho utilizzate per le luci delle bici e sono ancora funzionanti nonostante la pioggia e le continue vibrazioni delle bici
