Uma lâmpada UV/LED seca o verniz gel e o gelinho em segundos – o verniz clássico quase não seca mais depressa com ela. Que lâmpada vale a pena para casa e o que os watts anunciados querem mesmo dizer.

Provada para verniz gel
SUNUV SUN2C
Uma das lâmpadas mais conhecidas para verniz gel em casa. Liga-se sozinha por sensor quando a mão está por baixo e tem temporizador de 10 a 90 segundos. Quatro dedos cabem juntos; o polegar vai à parte – como em quase todas as lâmpadas.
Lâmpada UV/LED compacta com três tempos. Menos equipamento do que a concorrência, mas de um fabricante estabelecido, com manual claro – agradável para começar.
Lâmpada grande com ecrã, sensor e tempos de 10 a 99 segundos. O formato deixa espaço para a mão inteira e até para os pés. Os 168 watts anunciados são um número de marketing, não o consumo real – o que vale para muitas lâmpadas desta gama.
Segundo o fabricante, 48 LED e temporizador até 120 segundos – o tempo longo é prático para géis de construção espessos. De resto, equipamento semelhante ao da Aokyom.
Redonda, branca e compacta – na bancada da casa de banho não parece saída de um salão de unhas. Quatro tempos. Boa para uma manicure de gel de vez em quando, pequena demais para os pés.
Se um verniz precisa de lâmpada, vem indicado no frasco. «Efeito gel» não quer dizer que endureça com luz.
Verniz
Como endurece
O que ajuda
Verniz clássico
Os solventes evaporam
Camadas finas, top coat de secagem rápida, ar frio
Verniz gel / gelinho
Endurece com luz UV
Lâmpada UV/LED com o comprimento de onda certo
Gel de construção
Endurece com luz UV
Lâmpada com tempo longo (90–120 segundos)
Verniz «efeito gel» sem lâmpada
Evaporação, como o verniz clássico
Não precisa de lâmpada – top coat da mesma gama
O que avaliamos
UV e LED
As lâmpadas modernas combinam as duas fontes de luz e assim secam quase todos os géis. As lâmpadas só LED não secam todos os vernizes – na dúvida, segue a indicação do fabricante do verniz.
Watts
Números como «168 W» ou «180 W» são, nas lâmpadas baratas, valores publicitários. Para casa, chegam 36 a 48 watts de potência real.
Temporizador
Pelo menos 30 e 60 segundos, de preferência também um tempo curto para fixar. Quem usa gel de construção precisa de 90 a 120 segundos.
Sensor
Um sensor de movimento liga a lâmpada automaticamente – prático quando a outra mão já está pintada.
Tamanho
Quatro dedos devem caber deitados sem tocar nas paredes. Para os pés, é preciso uma lâmpada com a base aberta.
Quase nada. O verniz clássico endurece porque os solventes evaporam. O calor da lâmpada acelera isso muito pouco; ajudam mais as camadas finas e um top coat de secagem rápida.
Quanto tempo tem o verniz gel de ficar na lâmpada?
Em geral, 30 a 60 segundos por camada numa lâmpada UV/LED. O que conta é a indicação do fabricante do verniz – secar pouco tempo deixa camadas pegajosas que lascam depressa.
As lâmpadas UV para unhas fazem mal à pele?
As lâmpadas emitem luz UV-A. A exposição por utilização é baixa, mas acumula-se com o uso frequente. Protetor solar nas costas das mãos ou luvas sem dedos são uma precaução simples.
O que significam os watts nas lâmpadas de unhas?
Em muitas lâmpadas baratas, são um valor publicitário, não o consumo real. O decisivo é o comprimento de onda, a distribuição dos LED e um tempo adequado.
